Comprehensive Guide to Solving and Patching N×N×N Rubik's Cube Algorithms in Python

For large N (e.g., 100x100x100), practical solvers use and move sequences rather than optimal solvers.

The two-phase algorithm works by first solving the cube into a subgroup of possible states (Phase 1), then solving that subgroup optimally (Phase 2). The result is a solution that is very close to optimal (often 20 moves or fewer). nxnxn rubik 39scube algorithm github python patched

Finding an optimal move path using Breadth-First Search (BFS) or Depth-First Search (DFS) exhausts the Python call stack and causes rapid memory expansion. Comprehensive Guide to Solving and Patching N×N×N Rubik's
