That commit message was a lie, it did not improve performance but actually reduce it significantly... I had accidentally added a lot of complexity due to the std::list data structure. this approach might seem more redundant, but it's much faster with rectangles (like 100x faster) and doesn't seem to make a difference in the other cases.

dependencies
for the visual graphic display SFML is needed (https://www.sfml-dev.org/download/sfml/2.5.1/) if you want to compile the program on your own, the deployed release uses static linkage.
program arguments
-v mode with enabled visualization
-akl using Akl-Toussaint heuristic beforehand
https://en.wikipedia.org/wiki/Convex_hull_algorithms#Akl%E2%8
-f <filename> read random numbers from file
-rngcount <count> generates count random float values
-rngmode <mode> if generating float values this specifies the mode:
1. random numbers in screen range
2. numbers are ordered as rectangle
3. numbers are ordered as circle around screen center
-runs <count> runs performance mode multiple times
-stepsize <size> time between autosteps; if 0 or not provided -> manual steps
