Chess is hard even for a single player

N. R. Aravind, Neeldhara Misra, Harshil Mittal

We introduce a generalization of "Solo Chess", a single-player variant of the game that can be played on chess.com. The standard version of the game is played on a regular 8 x 8 ch…

Perfectly Matched Sets in Graphs: Parameterized and Exact Computation

N. R. Aravind, Roopam Saxena

In an undirected graph , we say is a pair of perfectly matched sets if and are disjoint subsets of and every vertex in (resp. ) has exactly one…
