In order to compare the performance of the method given in the paper and the penalty function algorithm, we use the same computer (CPU: AMD Athlon II M340 2.
In equation (6) if the pressure or speed be in allowed limit the penalty function will be zero.
The second edition incorporates changes in the field by describing a basic particle filter that implements Bayesian single-target recursion, presenting three algorithms that provide approximate solutions to multiple-target tracking problems, including new information on multi-target intensity filters and the maximum a posteriori penalty function technique, and making other changes.
Equality constraint can be incorporated into fitness function, while inequality constraint needs penalty function to be incorporated into fitness function for optimization solution.
Penalty function method is a technique which is used to solve the constrained optimization problems.
In this algorithm there are (1) local--the penalty function is applied to the expert--and (2) global--the penalty function is applied to the whole individual penalty--functions applied.
Two algorithms are used in this paper: a traditional genetic algorithm with penalty function and a random-weighted genetic algorithm with a binary selection scheme.
In this proposal, no penalty function is needed, and some extra mechanisms are defined to allow the approach to work in cases in which there are no feasible solutions in the initial population.
We thus defined a penalty function proportional to the difference in METAVIR units between stages (the penalty function was 0.
The penalty function biases upward the estimate of value for a query point in a manner inversely proportional to the data density, which discourages the optimizer from driving the system into unexplored regions.
