Random generation and optimal solution

5 次查看(过去 30 天)
Hello all
I used the random generation equation to generate a random solution for a meta-heuristic algorithm. Now I try to choose the best optimal solution among the solutions I get and use this optimal solution for another equation. But to do it? Thank you for your help

To select the best optimal solution from randomly generated candidates in a meta-heuristic algorithm:
  1. Define the Objective Function: Clearly specify what you're optimizing (minimize or maximize). Incorporate any constraints directly into this function or apply penalties for violations.
  2. Generate Diverse Solutions: Use your random generation method to create a wide range of initial solutions. Diversity helps explore the solution space effectively and avoids premature convergence.
  3. Evaluate Each Solution: Apply the objective function to each candidate to compute its fitness.
  4. Select the Best Solution: Track the solution with the best fitness (lowest for minimization, highest for maximization). Optionally, repeat the process over several iterations using meta-heuristics like Genetic Algorithms or Simulated Annealing for better results.
  5. Use the Optimal Solution: Once identified, use this best solution in the next equation or application step.
function findBest(solutions, mode): // mode = "min" or "max"
best = None
bestFitness = +if mode == "min" else -
for s in solutions:
f = evaluate(s)
if (mode == "min" and f < bestFitness) or (mode == "max" and f > bestFitness):
bestFitness = f
best = s
return best
I hope this resolves your query!
