Abstract:
Summary In the paper we give a formalization in the Mizar system [2, 1] of the rules of an inference system for an extended Floyd-Hoare logic with partial pre- and post-conditions which was proposed in [7, 9]. The rules are formalized on the semantic level. The details of the approach used to implement this formalization are described in [5]. We formalize the notion of a semantic Floyd-Hoare triple (for an extended Floyd-Hoare logic with partial pre- and post-conditions) [5] which is a triple of a pre-condition represented by a partial predicate, a program, represented by a partial function wh

Abstract:
Nowadays, the methods of program-targeted management for the development of various socio-economic systems of complex structure, such as agricultural areas, have become universal. Therefore, the current tasks at hand are the verification of already created development programs and the development of "proper" programs for the development of such systems, by analogy with the verification and development of proper computer programs through developed disciplines in theoretical programming. In this paper, in order to solve the problem of verification of development programs for agricultural territo

Abstract:
AbstractBehavioral type and effect systems regulate properties such as adherence to object and communication protocols, dynamic security policies, avoidance of race conditions, and many others. Typically, each system is based on some specific syntax of constraints, and is checked with anad hocsolver. Instead, we advocate types refined with first-order logic formulas as a basis for behavioral type systems, and general purpose automated theorem provers as an effective means of checking programs. To illustrate this approach, we define a triple of security-related type systems: for role-based acce

Abstract:
Summary In this paper we present a formalization in the Mizar system [2, 1] of the correctness of the subtraction-based version of Euclid’s algorithm computing the greatest common divisor of natural numbers. The algorithm is written in terms of simple-named complex-valued nominative data [11, 4]. The validity of the algorithm is presented in terms of semantic Floyd-Hoare triples over such data [7]. Proofs of the correctness are based on an inference system for an extended Floyd-Hoare logic with partial pre- and post-conditions [8, 10, 5, 3].

Abstract:
In this paper, we investigate the axiomatic semantics of the projection temporal logic programming language MSVL. To this end, we employ Propositional Projection Temporal Logic (PPTL) as an assertion language to specify the desired properties. We give a set of state axioms and state inference rules. In order to deduce a program over an interval, we also formalise a set of rules in terms of a Hoare logic-like triple. These rules enable us to deduce a program into its normal form and from the current state to the next one. They also enable us to verify properties over intervals. In this way, an
