rubiks_cube

Rubik's cube solver using PDB, developed in C++.

Solution

• We'll be using three (3) different PDBs:
  • A PDB showing the distance from any given configuration of the eight (8) corners of the cube to the desired configuration (goal) of the corners.
  • A PDB showing the distance from any given configuration of six (6) (or seven (7) or eight (8)) edges of the cube to the desired configuration (goal) of said edges.
  • A PDB showing the distance from any given configuration of the remaining six (6) (or five (5) or four (4)) edges of the cube to the desired configuration (goal) of said edges.
• IDA*
