Solver algorithms — Cross, XCross, C+1 flow charts

The algorithm docs explain the engine behind Cross / XCross / Cross + 1 F2L: cube model, IDA*, F2L ranking — not a CFOP lesson.

What the diagrams cover

• Cube representation and moves.
• Basic Cross (QTM / IDA*) and Pro (ergonomic).
• XCross and Cross + 1 F2L (recognition + MCTS).

Open /thuat-toan, then compare with the Cross or XCross UI.
