A new crossover operator for single machine total weighted tardiness problem with sequence dependent setup times
(2012)The single machine total weighted tardiness problem with sequence dependent setup times is a challenging and heavily studied problem. This problem is NP-hard, so several heuristics have been proposed in the literature so ... -
New mathematical models for team formation of sports clubs before the match
(Springer, 2019)Coaches of sports clubs aim to form the team that optimally determines the roles of positions before the match. These types of decisions are referred to as the team formation problem, and they are critical for the sports ... -
A novel piecewise linear classifier based on polyhedral conic and max-min separabilities
(Springer, 2013)In this paper, an algorithm for finding piecewise linear boundaries between pattern classes is developed. This algorithm consists of two main stages. In the first stage, a polyhedral conic set is used to identify data ... -
Numerical optimization of a fin-tube gas to liquid heat exchanger
(Elsevier France-Editions Scientifiques Medicales Elsevier, 2012)The influence of plate fin, fin tube and protrusion parameters on heat transfer and pressure drop characteristics of a finned tube gas to liquid heat exchanger is examined in this study. The optimization of plate fin, fin ... -
