SOLVING A STEP FIXED CHARGE TRANSPORTATION PROBLEM BY A SPANNING TREE-BASED MEMETIC ALGORITHM

In this paper, we consider the step fixed-charge transportation problem (FCTP) in which a step fixed cost, sometimes called a setup cost, is incurred if another related variable assumes a nonzero value. In order to solve the problem, two metaheuristic, a spanning tree-based genetic algorithm (GA) and a spanning tree-based memetic algorithm (MA), are developed for this NP-hard problem. For compa...

A step toward systems metabolomics.

WHILE LEVELS OF GENES AND proteins provide information on a cell’s possibilities, the levels of metabolic intermediates provide a very direct indication of a cell’s current activities. Methods to monitor the levels of metabolites as well as the dynamic flux through metabolic pathways can be integrated to generate a systems-level understanding of the metabolic activity in a cell at a given time....
