How do cubers make their own algorithms for PLLs and OLLs?

[RadioactivCuber]

I have watched many videos and have seen every top cuber like felicks, mats and chris olson do their own algorithms for PLLs and there are so many algs for each PLL on speedsolving wiki. My question is, how do they make these algorithms.............do they use conjugates . Can anybody give me detailed answer and an example? Thank you

Sometimes doing moves and seeing what happens, sometimes using computer programs to search for algorithms. Common ones are Cube Explorer, ACube, and ksolve.

Another way is to come up with commutators for the case. Watch this long video to learn how:

i quess most fast cubers these days don't really make up their own algs ( the only people i can think of are the fast bld users and Mats).
