A Fixed Parameter Sublinear Time Approximation Scheme for Metric Min-Sum Clustering
Karthik C. S., Euiwoong Lee, Yuval Rabani +2
Metric -minsum clustering is a simple, natural, appealing density-based clustering criterion whose computational complexity remains poorly understood, despite the progress achie…
-distortion of Earth Mover Distances and Transportation Cost Spaces on High Dimensional Grids
Chris Gartland, Mikhail Ostrovskii, Yuval Rabani +1
We prove that the distortion of any embedding into of the transportation cost space or earth mover distance over a -dimensional grid is , wher…
Budget and Profit Approximations for Spanning Tree Interdiction
Rafail Ostrovsky, Yuval Rabani, Yoav Siman Tov
We give polynomial time logarithmic approximation guarantees for the budget minimization, as well as for the profit maximization versions of minimum spanning tree interdiction. In…
New Results on a General Class of Minimum Norm Optimization Problems
Kuowen Chen, Jian Li, Yuval Rabani +1
We study the general norm optimization for combinatorial problems, initiated by Chakrabarty and Swamy (STOC 2019). We propose a general formulation that captures a large class of c…
On Approximability of Min-Sum Clustering
Karthik C. S., Euiwoong Lee, Yuval Rabani +2
The min-sum -clustering problem is to partition an input set into clusters to minimize . Although $\ell_2^2…
Diversity in Evolutionary Dynamics
Yuval Rabani, Leonard J. Schulman, Alistair Sinclair
We consider the dynamics imposed by natural selection on the populations of two competing, sexually reproducing, haploid species. In this setting, the fitness of any genome varies…
