WebNov 11, 2024 · Energy optimization with a genetic algorithm uses the surrogate model as a fitness function with seven variables. These variables have a defined design search space to perform a function minimization that produces the least annual energy-consuming design model. Other methods can be used for optimizing the surrogate models. WebStep 4. Evaluation of fitness value of chromosomes by calculating objective function Step 5. Chromosomes selection Step 6. Crossover Step 7. Mutation Step 8. Solution (Best …
