Optimal solutions for the Rubik's Cube are solutions that are the shortest in some sense. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of outer-layer twists, called "face turns".
Competitors are given a scramble sequence, 3 cubes, pen, paper and 1 hour time to find the shortest solution. As you might know any cube state can be solved with 20 moves or less. The majority of cube states need 18 moves to be solved.
This guide on how to solve a Rubik’s cube for beginners gives an overview of the basic method, an introduction to Rubik’s cube algorithms, and even some advanced tactics for those of you looking for some tips to boost your speed.
Oct 30, 2016 · If the goal is to find the shortest solution to the 8-puzzle, DFS is indeed a very poor method. It's not a matter of faster or slower; DFS is not correct (it finds a solution, but it's not guaranteed to be the shortest solution). You could use BFS and that will work fine.
Apr 13, 2017 · The competitor with the shortest solution wins. In this 1 hour you can scramble and solve as many cubes as you want, try different tricks, and so on. Good people find sub 30 solutions quite regularly.

Oct 6, 2021 · Easily solution : transform b into two symbol then compare to a and c (like b=xy , ax= , yc= ...etc , but it won't be the shortest) Shortest solution : compare two symbol then transform into a new symbol not just let them disappear (like ab=x , xc= ...etc)
