A tag is a keyword or label that categorizes your question with other, similar questions. Using the right tags makes it easier for others to find and answer your question.
For questions on interfaces between a solver library and applications that allow to call user code at specific points in the solving process (e.g. on finding a new solution).
For questions related to the convex hull of a set, often (but not limited to) referring to the feasible region in optimization.
For questions related to applications of operations research models to energy systems.
For questions on constraints over random variables that need to be satisfied with a given probability.
For questions on the commercial constraint solver CPLEX CP Optimizer.
SCIP is a source-open solver for (among others) MILPs, MINLPs, ... ask questions about usage, bugs, interfaces, behavior.
For questions on experimentation in computational OR, for example, the performing, analysing and reporting of experiments.
For questions related to empirical or computational bounds that quantify how far the objective function value of a given solution is from the optimal objective function value.
For questions related to journals that publish papers related to Operations Research.
For questions relating to the Computational Infrastructure for Operations Research (COIN-OR).
For questions on matchings, i.e. sets of disjoint edges of an undirected graph.
For questions related to Lagrangian decomposition, an optimization method in which one or more decision variable is doubled, the new variable is set equal to the original variable via a constraint, an…
For questions relating to the mathematical or geometric structure known as a cone.
Use on questions that relate to teaching, whether in academia or otherwise.
For questions related to probability distributions used to model demands for products or services, e.g., in an inventory or supply chain optimization context.
