The roulette wheel selection (also known as fitness proportionate selection) is a function used by genetic algorithms for selecting potentially useful solutions for recombination. The crossover individual probability is computed based on the individual’s fitness divided by the sum of all population fitness. The following is the formula for it: where pi is the probability […]

Genetic Algorithm Python Example
Genetic Algorithms (GA) are a subclass of evolutionary algorithms that emulate natural evolution. Darwin’s theory on natural selection states that the fittest individuals are the ones which reproduce.

I wish to preach, not the doctrine of ignoble ease, but the doctrine of the strenuous life, the life of toil and effort, of labor […]
Citizenship in a Republic By Theodore Roosevelt (1910)
Here there are some quotes from the Citizenship in a Republic By Theodore Roosevelt that I found were worth keeping and reflecting upon. Each of the following paragraphs represents a segment. It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds […]
