At first several applications of this problem class are described and mathematical formulations of QAPs are given. Then some exact solution methods and good heuristics are outlined. Their computational behaviour is illustrated by numerical results. Further recent results on the asymptotic probabilistic ...
Ant colony algorithm is applied to solve unmanned aerial vehicle(UAV) cooperative multi-task assign-ment problem(CMTAP).Based on the generic formulation of CMTAP,an extended mathematical formulation for the UAV CMTAP is presented,which takes the dynamic time window constraints and the capabilities ...
Problem Formulation • Problem formulation or modeling is the process of translating a verbal statement of a problem into a mathematical statement. • Formulating models is an art that can only be mastered with practice and experience.

We have used a precise mathematical formulation in which the frequency plans are evaluated using accurate interference information coming from a real GSM network. We have developed an improved version of the scatter search (SS) algorithm in order to solve this problem. After accurately tuning this ...
