it's actual (adaptive) nelder-mead, done on a 5-cell that's rotated and projected down to 3D :)

...except with two sources of randomness:

• vertices are randomly nudged by a tiny amount every step, since otherwise the simplex shrinks too much and floating point precision makes the simplex and sphere jitter (which looks great for a bit, until it goes off screen)
• the gaussian noise in the objective function is to randomize the possible moves after a while, since otherwise the algorithm gets mostly stuck on reflect/contract
  

long runs of the same move are also condensed to make gameplay better (that's what the yellow numbers on some of the tiles are)
