Top new questions this week: |
I am a network engineer working with optimization models. In some transportation and logistics models, especially when there are economies of scale, the cost function becomes concave. I am not sure ... |
Greatest hits from previous weeks: |
I am reaching out for help because I feel lost in my current work situation and would like to hear advice from you guys. Currently, as an operations research optimization algorithm engineer at a small ... |
I have found a PowerPoint presentation in which the presentor Hall claims instances could be of the size of 108 in variables and constraints to be solved today. I assume that he meant sparse problems. ... |
Yesterday I came across a post on here, where one answer claims that C++ can be up to 10,000 times faster than Python under specific circumstances. In the light of this runtime superiority, why are ... |
There is a quote from John Tukey in one of his papers on data analysis Far better an approximate answer to the right question, which is often vague, than an exact answer to the wrong question, ... |
The question here discusses the two different use of "big-M method", where one of them is the big-M in logical constraints and linearization in (mixed-)integer programming problems (that's what I'm ... |
What is the difference between the two common optimization models for electricity systems, optimal power flow (OPF) and economic dispatch (ED)?I've heard people say that ED is just a multi-period ... |
The terms "soft constraints" and "hard constraints" are used in the context of optimization modeling.Is there any standard way to figure out which is which in some of the complicated models? |
