Algebraic tools for nonlinear integer programming problems 1: Getting started.

Coauthors: F. J. Castro, J. Gago, M. I. Hartillo, J. Puerto


In this first talk we revisit a classical approach for obtaining exact solutions of some nonlinear integer problems. We treat the case of linear objective function with linear and nonlinear constraints.
Besides the test-set of some linear subpart of the problem, calculated via Gröbner bases (sometimes obtained explicitly without computation), we propose some extra ingredients. We show how to use information from the continuous relaxation of the problem, add quasi-tangent hyperplanes and use penalty functions as a guide in the search process.

  There are three major facts that should be watched out for in all payday loans in the United States. Since its introduction in the market buying Cialis can be exclusively in pharmacy chains with a prescription from a doctor. I agree that this is very inconvenient and takes a lot of time and effort.
