ISMP!  WI will be speaking about complexity in mixed integer nonlinear programming at a session at the International Symposium on Mathematical Programming in Montreal in July.  I'm also organizing a session on Advances in Mixed Integer Programming theory.

6.2.24

Summer School Lecture!  With Dr. Santanu Dey and Dr. Phillip Richard, we will be giving a summer school session on Cutting Planes prior to the Mixed Integer Programming Workshop, 2024.

2.7.24 

Paper Accepted!  With Dr. Nicholas Goedert, Dr. Laurel Travis, and Matthew Pierson,  our paper "Asymmetries in Potential for Partisan Gerrymandering" has been published in Legislative Studies Quarterly.  See the paper here.

1.30.24 

Paper Accepted!  With Dr. Ben Beach (former student), Lukas Hager, Robert Burlacu, and Andreas Barman, our paper Enhancements of Discretization Approaches for Non-Convex Mixed-Integer Quadratically Constraint Quadratic Programming Part I is published in Computational Optimization and Applications.  This paper handles new techniques for discretizing quadratics.  Part II will be available shortly.

10.25.23

Paper Accepted!  With Dr. Ben Beach (former student), William Chapin, Samantha Chapin, and Dr. Erik Komendera, our paper "Force-Controlled Pose Optimization and Trajectory Planning for Chained Stewart Platforms" has been approved for production and accepted for publication in Frontiers in Mechanical Engineering, section Digital Manufacturing.  

This paper uses quadratically constrained quadratic programming to optimize robotics movements developed in the FASER lab.
