A Tight Bound for Conflict-free Coloring in terms of Distance to Cluster

Sriram Bhyravarapu, Subrahmanyam Kalyanasundaram

Given an undirected graph , a conflict-free coloring with respect to open neighborhoods (CFON coloring) is a vertex coloring such that every vertex has a uniquely colore…

Conflict-Free Coloring of Star-Free Graphs on Open Neighborhoods

Sriram Bhyravarapu, Subrahmanyam Kalyanasundaram, Rogers Mathew

Given a graph, the conflict-free coloring problem on open neighborhoods (CFON) asks to color the vertices of the graph so that all the vertices have a uniquely colored vertex in it…

Combinatorial Bounds for Conflict-free Coloring on Open Neighborhoods

Sriram Bhyravarapu, Subrahmanyam Kalyanasundaram

In an undirected graph , a conflict-free coloring with respect to open neighborhoods (denoted by CFON coloring) is an assignment of colors to the vertices such that every vertex…

Bipartitioning Problems on Graphs with Bounded Tree-Width

N. R. Aravind, Subrahmanyam Kalyanasundaram, Anjeneya Swami Kare

For an undirected graph G, we consider the following problems: given a fixed graph H, can we partition the vertices of G into two non-empty sets A and B such that neither the induc…
