Backward Analysis via over-Approximate Abstraction and under-Approximate Subtraction,ation of a greatest fixed point, or complementation of a least fixed point, are often difficult to apply successfully. Our approach relies on a different decomposition of the weakest precondition of loops. We exchange the greatest fixed point for the computation of a least fixed point above a recurr

Cyclic Abduction of Inductively Defined Safety and Termination Preconditions,definitions in separation logic. Cyclic abduction essentially works by searching for a . of the desired property, abducing definitional clauses of the precondition as necessary in order to advance the proof search process..We provide an implementation, ., of our cyclic abduction method, based on a s

Expectation Invariants for Probabilistic Program Loops as Fixed Points,erators. Whereas, traditional program analysis uses Floyd-Hoare style invariants to over-approximate the set of reachable states, our approach synthesizes invariant inequalities involving the expected values of program expressions at the loop head. We first define the notion of expectation invariant

An Abstract Domain to Infer Octagonal Constraints with Absolute Value,gram, is one of the most commonly used numerical abstractions in practice, due to its quadratic memory complexity and cubic time complexity. However, the octagon domain itself is restricted to express convex sets and has limitations in handling non-convex properties which are sometimes required for
