Hello, I'm pleased to announce the second release of the PyCPX wrapper for IBM's CPlex Optimizer Suite. This second release fixes several bugs and vastly optimizes the model construction stage, particularly for large models. PyCPX is a python wrapper for the CPlex optimization suite that focuses on ease of use and seamless integration with numpy. It allows one to naturally specify linear and quadratic problems over real, boolean, and integer variables. For documentation and examples, please see the website: http://www.stat.washington.edu/~hoytak/code/pycpx/index.html. Please send me any comments, questions and suggestions! I am quite open to feedback. Thanks, --Hoyt ++++++++++++++++++++++++++++++++++++++++++++++++ + Hoyt Koepke + University of Washington Department of Statistics + http://www.stat.washington.edu/~hoytak/ + hoytak@gmail.com ++++++++++++++++++++++++++++++++++++++++++
