Improved Euclidean Shallow Light Trees
Hung Le, Shay Solomon, Cuong Than +3
For parameters , a spanning tree of a weighted graph rooted at a designated vertex is called an -shallow-light tree (SLT) if (i) for every vertex ,…
Dynamic Dominating Set in Uniformly Sparse Graphs
Anton Bukov, Shay Solomon
In the dynamic {\em minimum dominating set (MDS)} problem, the goal is to efficiently maintain an approximate MDS in an -vertex graph with vertex costs in undergoing e…
Optimal Bounds for Spanners and Tree Covers in Doubling Metrics
An La, Hung Le, Shay Solomon +4
It is known that any -point set in the -dimensional Euclidean space , for , admits: 1) a -spanner with maximum degree a…
Tree-Like Shortcuttings of Trees
Hung Le, Lazar MilenkoviÄ, Shay Solomon +1
Sparse shortcuttings of trees -- equivalently, sparse 1-spanners for tree metrics with bounded hop-diameter -- have been studied extensively (under different names and settings), s…
Approximating Euclidean Shallow-Light Trees
Hung Le, Shay Solomon, Cuong Than +2
For a weighted graph and a designated source vertex , a spanning tree that simultaneously approximates a shortest-path tree w.r.t. source and a minimum…
Towards a Unified Theory of Light Spanners I: Fast (Yet Optimal) Constructions
Hung Le, Shay Solomon
Seminal works on light spanners over the years provide spanners with optimal lightness in various graph classes, such as in general graphs, Euclidean spanners, and minor-free graph…
