# Prototype for a new optimal solver
Work in progress.
TODO:
* transformations (internal only, not in cube.h)
* coordinates: co, eo, epsep, cpsep_sym, cocpsep_sym, cphtr_sym, cocphtr_sym
* pruning tables (1 bit per entry + fallback)
* solve.c
Optimizations:
* multi-move (up to 4/5 moves at once)
* avx2_cube.c
Things I need to learn:
* Use AVX2 instructions, in particular
[_mm256_shuffle_epi8](https://www.intel.com/content/www/us/en/docs/cpp-compiler/developer-guide-reference/2021-10/mm256-shuffle-epi8.html))
* Inspect compiled assembly
* Use valgrind tool cachegrind and other profiling tools
