Genetic Algorithm
A genetic algorithm is a search-based optimization technique based on the principles of genetics and natural selection. It is frequently used to find optimal or near-optimal solutions. we can apply the genetic algorithm that is not well suited for the standard optimization algorithm.

Basics of Probability and Statistics Week 1 Challenge
1. Why there is a difference in the formula of variance for population and sample The main difference between population variance and sample variance relates to the calculation of variance. Variance is calculated in five steps. First mean is calculated, then we calculate deviations from the mean, and thirdly the deviations…
