Publisher Summary This chapter presents an introduction to some of the basic issues in the study of program logics. The chapter describes various forms of first-order Dynamic Logic and discusses their syntax, semantics, proof theory, and expressiveness. The chapter discusses the power of auxiliary data structures such as arrays and stacks, and a powerful assignment statement called the nondeterministic assignment. Program logics differ from classical logics in that truth is dynamic rather than static. In classical predicate logic, the truth value of a formula is determined by a valuation of its free variables over some structure. The valuation and the truth value of the formula it induces are regarded as immutable. In program logics, there are explicit syntactic constructs called programs to change the values of variables, thereby changing the truth values of formulas. There are two main approaches to modal logics of programs: (1) the exogenous approach, exemplified by Dynamic Logic and its precursor, the Partial Correctness Assertions Method; and (2) the endogenous approach, exemplified by Temporal Logic and its precursor, the Inductive Assertions Method.read more

Abstract Model Checking with SOFL Hierarchy
TL;DR: This paper presents a new abstract model checking approach for efficient verification of software in large scale by utilizing SOFL hierarchy, and within this approach, programs are verified from the high-level to low-level structures, and the state space throughout the verification can be effectively controlled.

A Probabilistic Model Checking Approach to Investigate the Palytoxin Effects on the Na + /K + -ATPase
TL;DR: It is discovered that high concentrations of ATP could inhibit PTX action, therefore individuals with ATP insufficiency, such as brain disorders (i.e. stroke), are more susceptible to the toxin.

Interference Analysis for Dependable Systems Using Refinement and Abstraction
TL;DR: A two-layered modal specification notation will allow the specification of services and protocols for distributed dependable systems and their properties and will play the key roles in an integrated development and analysis framework.

The temporal logic of programs
TL;DR: A unified approach to program verification is suggested, which applies to both sequential and parallel programs, and the main proof method is that of temporal reasoning in which the time dependence of events is the basic concept.

Propositional dynamic logic of regular programs
TL;DR: A formal syntax and semantics for the propositional dynamic logic of regular programs is defined and principal conclusions are that deciding satisfiability of length n formulas requires time d n /log n for some d > 1, and that satisfiability can be decided in nondeterministic time cn for some c.
