A slight increase in the amount of fitness value when the goal is to minimize

[zsbeheshti]

Dear all,

I use PyGAD for minimization (so I multiply the fitness function by the negative); Therefore, as the generations go forward, the fitness value of the best solution should decrease. But sometimes it increases by about 0.00000005 compared to the previous output. What is the reason?

PyGAD only works for maximization problems. Please formulate the fitness function to be a maximization function instead.
