Fractal algorithm
Fractal algorithms were algorithms used in creating computer-generated images. Using either an iterative or recursive process, simple geometric shapes were divided and replaced by smaller versions of themselves. 

When Dr. Lewis Zimmerman used a fractal algorithm to realign The Doctor's holographic matrix after it started to degrade while on Jupiter Station in 2377, it was mentioned that they were "notoriously unstable in the hands of a novice". ()

Later that year, Seven of Nine used fractal algorithms in conjunction with Borg sensors to locate "funnels" which the  could use to escape . ()
