Parameterized Complexity of Fair Coloring Problem

Ramin Javadi, Hossein Shokouhi

Given a graph , a (proper) -coloring for is a vertex coloring with colors such that every two adjacent vertices receive different colors. Suppose that the verte…

Parameterized Complexity of Fair Many-to-One Matchings

Ramin Javadi, Hossein Shokouhi

Given a bipartite graph , a left-perfect many-to-one matching is a subset such that each vertex in is incident with exactly one edge in . If $…

Parameterized Complexity of the Star Decomposition Problem

Sahab Hajebi, Ramin Javadi

A star of length is defined as the complete bipartite graph . In this paper we deal with the problem of edge decomposition of graphs into stars of varying l…

On the Parameterized Complexity of the Acyclic Matching Problem

Sahab Hajebi, Ramin Javadi

A matching is a set of edges in a graph with no common endpoint. A matching M is called acyclic if the induced subgraph on the endpoints of the edges in M is acyclic. Given a graph…

On the Parameterized Complexity of Sparsest Cut and Small-set Expansion Problems

Ramin Javadi, Amir Nikabadi

We present a parameterized dichotomy for the \textsc{-Sparsest Cut} problem in weighted and unweighted versions. In particular, we show that the weighted \textsc{-Sparsest Cu…

On Complexity of Isoperimetric Problems on Trees

Amir Daneshgar, Ramin Javadi

This paper is aimed to investigate some computational aspects of different isoperimetric problems on weighted trees. In this regard, we consider different connectivity parameters c…
