A fast algorithm for near cost optimal line plans

Bussieck, Michael R.; Lindner, Thomas; Lübbecke, Marco E. - In: Mathematical Methods of Operations Research 59 (2004) 2, pp. 205-220

We consider the design of line plans in public transport at a minimal total cost. Both, linear and nonlinear integer … programming are adequate and intuitive modeling approaches for this problem. We present a heuristic variable fixing procedure …

Equivalent Formulations of Nonlinear Integer Problems for Efficient Optimization

Kettani, Ossama; Oral, Muhittin - In: Management Science 36 (1990) 1, pp. 115-119

The linearization technique of Glover, which seems to be the most efficient one appearing in the literature, requires the addition of n new continuous variables (unconstrained in sign) and 4n new linear constraints to equivalently represent a 0-1 "quadratic" integer problem with n variables....
