PROFILE
Can Cebeci
Can Cebeci contributed targeted bug fixes to the Z3Prover/z3 repository, focusing on improving the robustness and correctness of the SMT solver core. Over two months, Can addressed edge cases in partial function interpretation for finite domains by ensuring else_value assignment, and stabilized solver relevancy propagation under case split strategies. These changes involved algorithm implementation and code refactoring in C++, with an emphasis on functional programming and solver development. The work demonstrated a deep understanding of SMT solver internals, addressing subtle failure modes and enhancing reliability for complex reasoning tasks, resulting in a more stable and predictable solver for end users.

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.
