SCIP
Welcome! SCIP is currently one of the fastest non-commercial solvers for mixed integer programming (MIP) and mixed integer nonlinear programming (MINLP). It is also a framework for constraint integer programming and branch-cut-and-price. It allows for total control of the solution process and the access of detailed information down to the guts of the solver. By default, SCIP comes with a bouquet o

My primary research interests are in the areas of mathematical programming. I have been working on design and analysis of efficient algorithms for discrete optimization concerning matroids and submodular functions. I am also interested in applications of discrete optimization techniques to algebraic/numerical computation that arises in systems analysis and control. Research Institute for Mathemati
SELECT Lab::Tutorial at ICML 2008: Beyond Convexity - Submodularity in Machine Learning
Beyond Convexity: Submodularity in Machine Learning Description Convex optimization has become a main workhorse for many machine learning algorithms during the past ten years. When minimizing a convex loss function for, e.g., training a Support Vector Machine, we can rest assured to efficiently find an optimal solution, even for large problems. In recent years, another fundamental problem st

Minimisation – Mailund on the Internet
Mailund on the Internet Computer science, bioinformatics, genetics, and everything in between Just for something to do on a lazy Sunday afternoon – where the only “excitement†was voting for the EU parliament (and the law concerning the succession to the Danish throne that won’t be relevant for the next two generations) – I played with R a little bit.
