Solver Race Public Lanes

Browser reference lanes · imported C11 solvers

Four live reference lanes run beside imported C11 solvers. C source is compiled locally to WebAssembly, executed in a fresh worker and checked by the page before a positive result is accepted.

Paradox SLS

Python + C11 paradox-scored local search

A witness-producing local-search implementation in Python and C11. Its published paradox component selects every permanent move, and every returned positive assignment is checked independently.
