Rules for Identifying the Initial Design Points for Use in the Quick Convergent Inflow Algorithm

摘要

The starting point of search is an important factor in optimal design construction as a poor starting point may require a longer time before convergence is reached. Hence the location of the initial design points for use in the Quick Convergent Inflow Algorithm on segmented regions is examined with the aim of developing useful criteria for identifying the initial design points. Proportional allocation of design points to go into the initial design measures is proposed. The allocation of 100% vertex points, 100% boundary points and 100% boundary points as well as the allocation of 50% vertex and 50% boundary points, 50% vertex and 50% interior points and 50% interior and 50% boundary points are investigated. Results show that a combination of design points comprising of 50% vertex points and 50% interior points or 50% vertex points and 50% boundary points forms helpful rules in identifying the initial design points for use in the Quick Convergent Inflow Algorithm. With these combinations, a moderate number of iterations needed to reach the required optimal or near-optimal solution is maintained.
