The CODESSA software v2.6 were used to calculate descriptors from the produced electronic structural data and finally to get linear correlations between the calculated and experimental PAF receptor binding inhibitory activity values using either best multi linear (BMLR) or Heuristic method.
This volume explains one of those strategies; a heuristic method known as risk parity, which seeks to build a balanced portfolio such that risk is weighted equally across different assets (equities and bonds).
We construct a mathematical model based on this communication graph and solve the model by an enhanced heuristic method. The proposed heuristic method incorporates simulated annealing into genetic algorithm to improve the accuracy and speed of original genetic algorithm.
In order to solve this program, the heuristic method is presented, which uses information contained in optimal primal and dual solutions to the first-order relaxation [LP.sup.1].
The comparison of the objective function allows us to assess the advantage of using the exact method over the heuristic method. The comparison of the CPU time allows us to measure the added cost of using the exact method over the heuristic method.
