Global optimization of mixed-integer polynomial programming problems: A new method based on Grobner Bases theory

Mixed-integer polynomial programming (MIPP) problems are one class of mixed-integer nonlinear programming (MINLP) problems where objective function and constraints are restricted to the polynomial functions. Although the MINLP problem is NP-hard, in special cases such as MIPP problems, an efficient algorithm can be extended to solve it. In this research, we propose an algorit...

2nd Pakistan international biennial conference on Ramadan and health

The ninth month of Islamic calendar is known as Ramadan, in which fasting is obligatory for every adult man and woman, except in certain health conditions and during travelling. Since Islamic jurisprudence follows the lunar calendar, which is about 11 days shorter than the Gregorian, Ramadan falls in different seasons throughout the year. The duration of fasting hence may differ by 11 to 18 hou...

Strong duality and minimal representations for cone optimization

The elegant results for strong duality and strict complementarity for linear programming, LP , can fail for cone programming over nonpolyhedral cones. One can have: unattained optimal values; nonzero duality gaps; and no primal-dual optimal pair that satisfies strict complementarity. This failure is tied to the nonclosure of sums of nonpolyhedral closed cones. We take a fresh look at known and ...

Multiresponse surface optimization via Harmony search algorithm (Quality Engineering Conference Paper)

Response surface methodology is a common tool in optimizing processes. It mainly concerns situations when there is only one response of interest. However, many designed experiments often involve simultaneous optimization of several quality characteristics. This is called a Multiresponse Surface Optimization problem. A common approach in dealing with these problems is to apply desirability funct...
