Traveling salesman and vehicle routing problems with their variants, as classic combinatorial optimization problems, have attracted considerable attention for decades of …
This paper focuses on training implicit models of infinite layers. Specifically, previous works employ implicit differentiation and solve the exact gradient for the backward propagation …
We consider the use of decision trees for decision-making problems under the predict-then- optimize framework. That is, we would like to first use a decision tree to predict unknown …
Bridging logical and algorithmic reasoning with modern machine learning techniques is a fundamental challenge with potentially transformative impact. On the algorithmic side, many …
Optimization problems with nonlinear cost functions and combinatorial constraints appear in many real-world applications but remain challenging to solve efficiently compared to their …
