Visualization

Evoasm provides means to visualize loss functions and found programs.

require 'evoasm/x64'

Evoasm.log_level = :warn

  [5, 1] => 1,
  [15, 5] => 5,

  [16, 8] => 8,
  [16, 2] => 2,

Loss Functions

Loss functions can be visualized by using Evoasm::Population#plot which will plot the loss function using Gnuplot. If a filename is provided, the loss function graph is saved to file. Otherwise, a window will open.
