Research summary

I am working in both theory and application of mathematical programming, knowledge discovery and discrete algorithm areas. The on going researches are related to the linear and nonlinear programming (improved the current methodologies and algorithms), the simulation optimization, class imbalance problem (Safe-level SMOTE, DBSMOTE), datamining techniques and algorithms (Multi-hyperplane scoring model), combinatorial analysis and advanced algorithms (Successive different sorting, Predecessor and Successor quicksort). I incorporate Mathematics and Mathematical programming concept such as linear programming, network programming, nonlinear programming, mathematical logic, machine intelligent and statistical techniques in order to solve problems in broad areas.
