I am taking a graduate level simulation course and I am looking for an interesting simulation topic to work on. If you have an idea or you would like to simulate your current probl …

I'm interested in hearing methods OR methods for fraud prediction. I'm aware of the classical methods like Logistic Regression. Perhaps there are some other methods.

e.g. specialized algorithms for mincost network flows, max flows, generalized network flows, etc. Do such projects exist or are they plans for this?

I am wondering if you know good references to learn about submodularity. I want to know the basics and perhaps some applications. Other references about developing algorithms for …

I've been working on the Analytics X Prize, which deals with predicting homicide rates. I find that I naturally look forward to new datapoints that to validate my model. Unfortunat …

I have a paper that seems like good fit for CP-AI-OR but the people whose work I am primarily building upon have all published in places like Management Science, EJOR, C&OR et …

I'd like to ask a Reddit style question. I am wondering: what is your favorite online video related to OR? Links are greatly appreciated :)

Hey, When looking through Coin-Or, I found they were referring to a constraint type called "free constraint". For instance here. Does any one know what a free constraint is? Tha …

With regards to this blog post. I have collected a number of datasets for different contributing variables to homicide incidents. I would like to know which of these variables is s …

I run an "OR Implementations" course where students do a project. Normally the project requires modeling a linear or integer program, implementing it (within AIMMS this year), and …

Inspired by a question on math overflow, let me ask: "Do good operations research jokes exist?" Alternatively, "Do bad operations research jokes exist?"

In my government office, we use Harvey Greenberg's ANALYZE program to examine LP results, especially shadow prices and their relationship to the LP matrix. Can you suggest some mor …

Hi all, I'm glad to inform you about release of OpenOpt 0.27 (numerical optimization framework), FuncDesigner 0.17 (CAS with automatic differentiation, convenient modelling of line …

I'm having trouble finding an answer to this question: How accurately does a 1-tree reflect the weight of an optimal tour? I know there are lots papers studying the various ways …

I am solving big optimization models (more than 100k variables) with the academic version of CPLEX but I'd like to see if I can find an open source alternative, I solve mixed integ …
