Welcome to Global Optimization Portal (GOP). This portal is aimed at providing efficient and practical algorithms for "Surrogate Model" based optimization applications in any dimensionality (1, 2,,,, 10, 20, 100 and more). The algorithms formulated at GOP are strictly based on mathematics. Therefore, they are independent of the nature of the application and can be applied to different areas of data analysis, for example, engineering design, scientific research, logistics and supply chain, manufacturing and factory operation, financial investment and trade-off analysis, and military operation. Note that the optimization software implemented at GOP is entirely web-based and facilitates online, interactive, and real-time computation. Just like RDIC, GOP is for education and training, and it is free to use to all visitors. In scientific simulation, one can search for the optimal solution according to the “objective function” defined for the system. Standard numerical optimization method is used to find the parameters which typically yield local optimum. Because of the sophistication of the simulation, the objective function which exists in multi-dimensional space can demand excessively high CPU time and cost to find the optimum through the iterative optimization process. To overcome this problem, one can use the approach of interpolation theory to acquire sampling values of the function, and build an analytic function (called interpolant or interpolating function) which approximates the objective function and is simpler to compute and manage. The interpolant established is the "Surrogate Model" of the original objective function. In consequence, one can replace the complex simulation code by the "Surrogate Model" in the optimum searching routine. The resulting gain from utilizing the interpolant can far outweigh the approximation incurred. | |
