Linear Discrepancy of Totally Unimodular Matrices
Let p [1, [ and cp = maxa[0,1]((1 - a)ap + a(1 - a)p)1/p. We prove that the known upper bound lindiscp(A) cp for the Lp linear discrepancy of a totally unimodular matrix A is as...

A Hyper-arc Consistency Algorithm for the Soft Alldifferent Constraint
This paper presents an algorithm that achieves hyper-arc consistency for the soft alldifferent constraint. To this end, we prove and exploit the equivalence with a minimum-cost flo...
