Supply Demand Optimization
Example:
from bejoor.economics_based import SupplyDemandOptimization
def rosenbrock_function(sol):
return sum(100 * (sol[i+1] - sol[i]**2)**2 + (sol[i] - 1)**2 for i in range(len(sol) - 1))
solution_vector = [{"type": "float", "lower_bound": -5, "upper_bound": 10}] * 7
optimizer = SupplyDemandOptimization(objective_function=rosenbrock_function, solution_vector_size=7,
solution_vector=solution_vector, optimization_side="min",
supply_probability=0.75, population_size=50, epochs=50)
optimizer.run()
print(f'Best Global Objective Value: {optimizer.global_best_objective_value}')
print(f'Best Global Solution: {optimizer.global_best_solution}')

-
target_objective_lower_bound
: Target Objective lower bound.
-
target_objective_upper_bound
: Target Objective upper bound.
-
population_size
: Number of individuals in the population.
-
epochs
