Nissy

A Rubik's cube solver and FMC assistant

Nissy is a command-line Rubik's cube solver. It can find optimal solutions for random positions using techniques from Herbert Kociemba's Cube Explorer and Tomas Rokicki's nxopt. With 4 cores at 2.5GHz and using about 3Gb of RAM, Nissy can find an optimal solution in about a minute on average.

Nissy aims at being a complete tool for FMC (Fewest Moves Challenge) practice. It can solve different steps of Thistlethwaite's algorithm (also know as DR/HTR) and cans use NISS (Normal-Inverse Scramble Switch).

You should use Nissy if:

• You want to analyze your DR solutions or check for multiple optimal (or sub-optimal) solutions for EO/DR/HTR or similar steps.
• You just want a Rubik's cube solver and you like command line interfaces.
• You want an alternative to Cube Explorer.
