A mature version of sweap is presented with novel features: a dual abstraction approach that improves its capabilities in proving unrealisability, support for nondeterministic and unbounded updates, more general initialization of variables, and equirealisable reductions for optimisation.
This work presents a technique for compiling the synchronous fragment of STL (SSTL) into synchronous observers in the dataflow language Lustre, and contributes an interactive visualiser that renders a property's three-valued verdict over an editable trace.

A metamorphic testing approach that uses semantics-preserving rewrite rules, focusing on floating-point special values and peep-hole optimizations, to uncover meaningful performance issues in SMT solvers' handling of floating-point formulas is proposed.
SynAct is presented, an adaptive closed-loop LLM reasoning--acting agent that iteratively diagnoses live synthesis reports and reasons over the current circuit state, retrieved tool knowledge, and historical optimization experience to issue targeted commands to improve timing.

Property-based testing of C programs can be automated by synthesizing random input generators from separation-logic specifications. Existing work in this space, such as the Bennet testing tool, uses randomized backtracking search, generating random values and checking them against constraints, backtracking on failure....

A novel hybrid approach that systematically derives upper bounds for the worst-case resource consumption of functional programs by combines dynamic symbolic execution to exhaustively explore all possible computation paths within a constrained input space with mixed-integer linear programming to derive empirically sound...

This work introduces DueList, an abstraction-refinement approach geared towards list reasoning, which is implemented on top of off-the-shelf SMT solvers and extends reasoning facilities of existing solvers, allowing to conclude about the (un)satisfiability of a larger range of problems, while outperforming existing sol...
