A team of researchers led by Rasmus Kinn of the Swiss Federal Institute of Technology in Zurich has created a near-perfect algorithm to calculate the maximum transport flows at the lowest cost in ...

• We propose a column generation algorithm for the separable piecewise linear approximation. • We show that the finite affine approximation can obtain the tightest bounds for 75% of the instances. • ...

This paper proposes a column generation algorithm for the multidepot vehicle routing problem with interdepot routes. This problem is an extension of the multidepot vehicle routing problem in which the ...
