Research in progress
Observatory is preparing and verifying real benchmark data. Public numbers will be released only after that verification is complete. Placeholder and test results stay hidden until then.
Logical decision procedures
Decision procedures across arithmetic, bit-vectors, arrays, floating point, and combined theories.
