Graph combination optimization
WebCombinatorial optimization problems are typically tackled by the branch-and-bound paradigm. We propose a new graph convolutional neural network model for learning branch-and-bound variable selection policies, which leverages the natural variable-constraint bipartite graph representation of mixed-integer linear programs.

WebWhen solving the graph coloring problem with a mathematical optimization solver, to avoid some symmetry in the solution space, it is recommended to add the following constraints. y k ≥ y k + 1 k = 1, …, K max − 1. Adding the above constraint forces to use preferentially color classes with low subscripts. WebDecentralized optimization is increasingly popular in machine learning for its scalability and efficiency. Intuitively, it should also provide better privacy guarantees, as nodes only observe the messages sent by their neighbors in the network graph. But formalizing and quantifying this gain is challenging: existing results are typically ...
