Worked on the Z3Prover/z3 repository, focusing on core solver reliability through targeted bug fixes in C++. Addressed robustness in partial function interpretation for finite domains by ensuring else_value assignment in the complete_partial_func logic, which improved correctness and reduced edge-case failures in SMT solving. Later, stabilized solver relevancy propagation under relevancy-dependent case split strategies, preventing incorrect disabling of relevancy and ensuring accurate solver behavior for complex reasoning tasks. Applied algorithm implementation, code refactoring, and functional programming skills to enhance the stability and reliability of SMT solvers, contributing to the foundational quality of the Z3 codebase over a two-month period.

Feb 1, 2025In February 2025, delivered a targeted bug fix for Z3's partial function interpretation, improving robustness and correctness of complete_partial_func in finite domains. The patch ensures else_value is always assigned, eliminating an edge-case where incorrect else_value handling could occur. The change landed with commit af270da785e1b15614951678e963a73c3e0d544d (Fix complete_partial_func for finite domains (#7547)). This work reduces failure modes in SMT solving for finite-domain models and strengthens overall reliability of the core engine.
