Although the simplex method is an excellent method for solving general linear problems, there are some that may efficiently be solved using other types of algorithms. This chapter will present the basics of the

A special and important network structured linear programming problem is the shortest path problem. Classical shortest path problems assume that there are unit of shipping cost or profit along an arc. In many real occasions, various attributes (various costs and profits) are usually considered in a...
linear programming; digraphs; shortest path Abstract In this paper, we are interested in the shortest path problem between two specified vertices in digraphs containing negative cycles. We study two integer linear formulations and their linear relaxations. A first formulation, close in spirit to a cl...

In most vehicle routing and crew scheduling applications solved by column generation, the subproblem corresponds to a shortest path problem with resource constraints (SPPRC) or one of its variants. This chapter proposes a classification and a generic formulation for the SPPRCs, briefly discusses compl...

Reconfiguring two shortest paths in a graph means modifying one shortest path to the other by changing one vertex at a time so that all the intermediate paths are also shortest paths. This problem has several natural applications, namely: (a) repaving road networks, (b) rerouting data packets...
In this post we implemented one more algorithm for solving all-pairs shortest path problem. Along the way, we learned basics of caching, reiterated on linear memory access, vectorisation and basic concurrency capabilities of .NET. We also saw with our own eyes how fast can be...
. By observing the user's decisions,the attacker needs to reveal some additional distributional informationassociated with the arcs emanated from the current user's position. It is shownthat the resulting multi-stage distributionally robust shortest path problemadmits a linear mixed-integer programming ...
