## What is the kociemba algorithm?

Kociemba’s Algorithm was an improvement on Thistlethwaite’s algorithm. Korf’s Algorithm was developed by Richard Korf in 1997. He claimed to optimally solve the cube by iterative deepening. With his algorithm he claimed one could solve the cube in 18 moves.

### Which algorithm is best for Rubik’s cube?

The most popular Speedsolving method is the CFOP (Cross, First 2 layers, Orientation of last layer, Permutation of last layer) a.k.a Fridrich Method. Unlike The beginner’s method, the Speedsolving method focuses mainly about solving the Rubik’s cube in the fastest and most efficient way, rather than the easiest way.

#### What is a pruning table?

Pruning configuration table helps prune data in union view nodes. The table holds the filter conditions that limit the result set when you execute a query on the union view node.

**What are two steps of tree pruning work?**

It is of 2 types prepruning and post pruning. The process of adjusting Decision Tree to minimize “misclassification error” is called pruning.

**What is Union pruning?**

Union node pruning allows the data sources in union nodes to be pruned. It is based on defined criteria that at runtime exclude specific data sources from the processing. This helps reduce resource consumption and benefits performance.

## Does Kociemba’s algorithm solve F2L first?

Of course, Kociemba’s Algorithm doesn’t solve F2L first. Once you’ve solved F2L, you can only do U moves without breaking up your progress, which is counterproductive.

### How to solve a cube with Kociemba?

Instead, Kociemba gets the cube into one of the states in “G1”, which means it has the following properties: All the corners are oriented (like in 3OP). All the edges are oriented (like in 3OP). All the middle layer edges are already in the middle layer. From there, you can solve the cube by using only .

#### What is the two-phase-algorithm?

Phase 1 of the Two-Phase-Algorithm uses a set of the 18 possible moves that, regardless of order or number of moves, cannot change the orientation of edge and corner pieces – G1.

**How is Kociemba different from iterative deepening?**

Instead of iterative deepening, Kociemba implementations usually use IDA*, which is iterative deepening combined with a heuristic. Instead of going through the solutions blindly, the algorithm tries to go down path that look like they might have a shorter solution.
