Abstract:

Alphabetical oracles are a collection of one-line prophecies organized in alphabetical order. Their existence is known solely through epigraphic evidence. Twelve inscriptions were discovered in southwestern Asia Minor, dating back to the 2 nd century AD. Among these, ten oracles were composed in iambic trimeter, while only two were in hexameter. The question arises: what meter was primarily employed for this form of divination? Inscriptions containing alphabetical oracles in hexameter were revealed in the Phrygian city of Hierapolis. Almost two-thirds of the hexametric oracle’s prophecies coin

A test oracle is a procedure that is used during testing to determine whether software behaves correctly or not. One of most important tasks for a test oracle is to choose oracle data (the set of variables monitored during testing) to observe. However, most literature on test oracles has focused either on formal specification generation or on automated test oracle construction, whereas little work exists for supporting oracle data selection. In this paper, we present a path-sensitive approach, PSODS (path-sensitive oracle data selection), to automatically select oracle data for use by expected

Abstract:

Bennett and Gill [1981] showed that P A ≠ NP A ≠ coNP A for a random oracle A , with probability 1. We investigate whether this result extends to individual polynomial-time random oracles. We consider two notions of random oracles: p-random oracles in the sense of martingales and resource-bounded measure [Lutz 1992; Ambos-Spies et al. 1997], and p-betting-game random oracles using the betting games generalization of resource-bounded measure [Buhrman et al. 2000]. Every p-betting-game random oracle is also p-random; whether the two notions are equivalent is an open problem. (1) We first show th

Abstract:

This paper contributes to the study of Tibetan oracles by analyzing a distinctive case of a contemporary Tibetan oracle living in exile in India. The oracular practice and personal history of Lhamo, or ‘Goddess,’ present several unusual features compared to other ethnographic accounts of Tibetan oracles. The ritual of possession is performed behind closed doors hidden from clients, and the medium typically engages in oracular ingestion multiple times during every trance. Her trance sessions also appear orderly and lack an intermediary figure who decodes the oracle’s enigmatic statements. What

Abstract:

Software testing is difficult, tedious, and may consume 28%–50% of software engineering labor. Automatic test generators aim to ease this burden but have important trade-offs. Fuzzers use an implicit oracle that can detect obviously invalid results, but the oracle problem has no general solution, and an implicit oracle cannot automatically evaluate correctness. Test suite generators like EvoSuite use the program under test as the oracle and therefore cannot evaluate correctness. Property-based testing tools evaluate correctness, but users have difficulty coming up with properties to test and u

Abstract:

A fundamental open question for oracles in blockchain environments is a determination of the amount of trust to be placed in the oracle. Oracles serve as intermediaries between a trusted blockchain environment and the untrusted external environment from where the oracles fetch data. As such, it is important to understand the uncertainty introduced by the oracle in the trusted blockchain environment and the implications of this uncertainty on blockchain performance. This paper develops a model for commoditization of trust. The model provides for dynamic trust environments that incorporates orac

We consider the problem of minimizing a smooth, Lipschitz, convex function over a compact, convex set using sub-zeroth-order oracles: an oracle that outputs the sign of the directional derivative for a given point and a given direction, an oracle that compares the function values for a given pair of points, and an oracle that outputs a noisy function value for a given point. We show that the sample complexity of optimization using these oracles is polynomial in the relevant parameters. The optimization algorithm that we provide for the comparator oracle is the first algorithm with a known rate

Abstract:

In this paper, we address clustering problems in scenarios where accurate direct access to the full dataset is impractical or impossible. Instead, we leverage oracle-based methods, which are particularly valuable in real-world applications where the data may be noisy, restricted due to privacy concerns or sheer volume. We utilize two oracles, the quadruplet and the distance oracle. The quadruplet oracle is a weaker oracle that only approximately compares the distances of two pairs of vertices. In practice, these oracles can be implemented using crowdsourcing or training classifiers or other pr

Whereas literary sources predating the New Kingdom may offer glimpses into certain aspects of oracle practices, they cannot serve as direct evidence of their existence and

We study to what extent quantum algorithms can speed up solving convex optimization problems. Following the classical literature we assume access to a convex set via various oracles, and we examine the efficiency of reductions between the different oracles. In particular, we show how a separation oracle can be implemented using O~(1) quantum queries to a membership oracle, which is an exponential quantum speed-up over the Ω(n) membership queries that are needed classically. We show that a quantum computer can very efficiently compute an approximate subgradient of a convex Lipschitz function. C

The factor oracle is a relatively new data structure for the set of factors of a string. It has been introduced by Allauzen, Crochemore, and Raffinot in 1999. It may recognize non-factors (hence the name "oracle") but its implementational simplicity and experimental behaviour are stunning; factor oracle based string matching has been conjectured optimal on average. However, its structure is not well understood. We take important steps in clarifying its structure by explaining how it can be obtained as a quotient of the trie of the set of factors.

The core of blockchain smart contracts is the execution of business logic code in a decentralized architecture with all executing nodes trusting and agreeing on the results. Smart contracts are unable to get data from the outside world on their own.

The usage of oracle returns the blockchain to its centralization problem and also exposes the blockchain to the possibility of introducing corrupt, malicious and erroneous data. This problem is call

We propose oracles that can handle any number k of failures. We show several tradeoffs between space, query time, and preprocessing time. In particular, for a directed weighted planar graph with n vertices and any constant k , we show an Õ( n )-size, Õ(√ n )-query-time oracle. 1 We then present a space vs. query time t

Lattice diagrams are regular two-dimensional structures that can be directly mapped onto a quantum circuit. We present a quantum oracle design methodology based on lattices. The oracles are designed with a proposed method using generalized Boolean symmetric functions realized with lattice diagrams. We also present a decomposition-based algorithm that transforms non-symmetric functions into symmetric or partially symmetric functions. Our

Abstract:

The Oracle relational database management system, with object-oriented extensions and numerous application-driven enhancements, plays a critical role worldwide in managing the exploding volumes of bioinformatics data. There are many features of the Oracle product which support the bioinformatics community directly already and there are several features which could be exploited more thoroughly by users, service vendors, and Oracle itself to extend that level of support. This paper will present an overview of Oracle features which support storage of bioinformatics data and will discuss extensibi

Abstract:

Service Oriented Architecture (SOA) has become a major application development paradigm. As a basic unit of SOA applications, Web services significantly affect the quality of the applications constructed from them. In the context of SOA, the specification and implementation of Web services are completely separated. The lack of source code and the restricted control of Web services limit the testability of Web services, and make the oracle problem prominent. In this context, can one alleviate the test oracle problem, or effectively and efficiently test such Web services even without oracles? It

Abstract:

Whereas the use of distributed ledger technologies has previously been limited to cryptocurrencies, other sectors—such as healthcare, supply chain, and finance—can now benefit from them because of bitcoin scripts and smart contracts. However, these applications rely on oracles to fetch data from the real world, which cannot reproduce the trustless environment provided by blockchain networks. Despite their crucial role, academic research on blockchain oracles is still in its infancy, with few contributions and a heterogeneous approach.

Abstract:

Abstract We are studying the punctual structures, i.e., the primitive recursive structures on the whole set of integers. The punctual categoricity relative to a computable oracle $$f$$ means that between any two punctual copies of a structure there is an isomorphism which togeteher with its inverse can be derived via primitive recursive schemes augmented with $$f$$. We will prove that the punctual categoricity relative to a computable oracle can hold only for finitely generated or locally finite structures. We will show that the punctual categoricity of finitely generated structures is exhause

Abstract:

Work on prepositional phrase (PP) attachment resolution generally assumes that there is an oracle that provides the two hypothesized structures that we want to choose between. The information that there are two possible attachment sites and the information about the lexical heads of those phrases is usually extracted from gold-standard parse trees. We show that the performance of reattachment methods is higher with such an oracle than without. Because oracles are not available in NLP applications, this indicates that the current evaluation methodology for PP attachment does not produce realist

Abstract:

We consider the notion of algorithmic randomness relative to an oracle. We prove that the probability β that a program for infinite computations (a program that never halts) outputs a cofinite set is random in the second jump of the halting problem. Indeed, we prove that β is exactly as random as the halting probability of a universal machine equipped with an oracle for the second jump of the halting problem, in spite of the fact that β is defined without considering oracles.

Abstract:

Active learning algorithms automatically identify the salient and exemplar samples from large amounts of unlabeled data and tremendously reduce human annotation effort in inducing a machine learning model. In a traditional active learning setup, the labeling oracles are assumed to be infallible, that is, they always provide correct answers (in terms of class labels) to the queried unlabeled instances. However, in real-world applications, oracles are often imperfect and provide incorrect label annotations. Oracles also have diverse expertise and while they may be noisy, certain oracles may prov

Abstract:

In a quantum computation, some algorithms use oracles (black boxes) for abstract computational objects. This paper presents an example for organizing Grover's quantum oracle by synthesizing several unitary gates such as CNOT gates, Toffoli gates, and Hadamard gates. As an example, we show a concrete quantum circuit for the knapsack problem, which belongs to the class of NP-complete problems. The time complexity of an oracle for the knapsack problem is estimated to be O(n2), where n is the number of variables. And the same order is obtained for space complexity.

The ancient Greeks believed in various predictions. One of the most ancient oracles of Ancient Greece was the Dodonian oracle, located in Northern Greece in a remote and mountainous region called Epirus. The main symbol of Dodona was the sacred oak, with the help of which the god Zeus announced his will. The Dodona oracle can be called the oracle of sounds: the rustle of the leaves of the sacred oak, the cooing of doves nesting on its branches, the sacred cauldrons, which, in contact with each other, emitted a melodic sound, the murmur of a spring with water that possessed miraculous powers.

Decentralized finance (DeFi) is by far the most popular application of blockchain technology. Despite the wide acceptance of new financial instruments and services, there are still many unexplored areas in the field. We dedicate this research to the understanding of one of the most crucial limitations of decentralized finance—oracles. DeFi protocols, as well as other blockchain applications, function in a closed environment and regularly need to fetch real-world information (e.g., assets’ prices)—the tool used for this purpose is called an oracle.
