Question
Using the genetic algorithm Python code base provided as a starting point, implement a genetic algorithm
to solve the knapsack problem. Please address the following by including the associated Python code
excerpts (as appropriate) and explanation of the code in the PDF file:
• createChromosome() logic
• crossover () logic
• Logic to compute chromosome fitness, e.g., any modifications to the evaluate() function
• roulette Wheel() logic
mutate() logic
• insert() logic
Apply the technique to the random problem instance and determine the best solution and objective value
using your revised algorithm. Test multiple versions of the GA (e.g., different number of generations,
population sizes, crossover rates, etc.)
