A Polynomial Combinatorial Algorithm for Generalized Minimum Cost Flow
We propose the first combinatorial solution to one of the most classic problems in combinatorial optimization: the generalized minimum cost flow problem (flow with losses and g...

Almost optimum placement legalization by minimum cost flow and dynamic programming
VLSI placement tools usually work in two steps: First, the cells that have to be placed are roughly spread out over the chip area ignoring disjointness (global placement). Then, i...

Convergent Lagrangian heuristics for nonlinear minimum cost network flows
We consider the separable nonlinear and strictly convex single-commodity network flow problem (SSCNFP). We develop a computational scheme for generating a primal feasible solution...

Fast Analytic Placement using Minimum Cost Flow
Many current integrated circuits designs, such as those released for the ISPD2005[14] placement contest, are extremely large and can contain a great deal of white space. These new...

Fast Minimum-Register Retiming via Binary Maximum-Flow
We present a formulation of retiming to minimize the number of registers in a design by iterating a maximum network flow problem. The retiming returned will be the optimum one whi...
