When Is Heterogeneous Distance-Decay Facility Location Tractable? A Structural Classification, Exact Methods, and a Real-World Study
Zhou He, T. C. E. Cheng, Jichang Dong
We study continuous planar facility location in which a demand point's captured value decays with distance, with the per-point decay scale varying across points. This heterogeneity…

Properly colored even cycles in edge-colored complete balanced bipartite graphs
Shanshan Guo, Fei Huang, Jinjiang Yuan +2
Consider a complete balanced bipartite graph and let be an edge-colored version of that is obtained from by having each edge assigned a ce…
