Genetic Algorithm For Global Maxima Minima

Check out the Application https://genetic-algorithm-for-global-maxima-minima.netlify.app/

This Application is made to find the Global Maxima or Minima for a given equation using a Genetic Algorithm. This Algorithm takes certain parameters for input and based on them finds the Global Maxima or Minima. The Performance Graph shows the Best Current Fitness and the best fitness found yet. The Y-Axis is the fitness while X-Axis is the Generation number. Learn More at https://genetic-algorithm-for-global-maxima-minima.netlify.app/

Instructions to Use the Site

1. The variables in equation must be named as x1,x2,x3 and so on.
2. The population size must be greater that 10 individuals.
3. The Cross Probability and Mutate Probability must be between 0 and 1.
4. Ignore Range is to find the Global Maxima. If Ignore Range is off, the algorithm finds the Local Maxima or Minima.

For Best Results:

Population Size = 100 Cross Probability = 0.3 Mutate Probability = 0.15.
