Fair, Efficient and Connected Allocations on Graphs
Susobhan Bandopadhyay, Anish Datta, Palash Dey +2
We study the classical and parameterized complexity of efficient connected allocation problems on graphs, where efficiency is measured by egalitarian and utilitarian welfare maximi…
Parameterized Complexity of Finding a Maximum Common Vertex Subgraph Without Isolated Vertices
Palash Dey, Anubhav Dhar, Ashlesha Hota +2
In this paper, we study the Maximum Common Vertex Subgraph problem: Given two input graphs and a non-negative integer , is there a common subgraph on at least …
Fair Distribution of Digital Payments: Balancing Transaction Flows for Regulatory Compliance

The concentration of digital payment transactions in just two UPI apps like PhonePe and Google Pay has raised concerns of duopoly in India s digital financial ecosystem. To address…
Shift Bribery over Social Networks
Ashlesha Hota, Susobhan Bandopadhyay, Palash Dey
In shift bribery, a briber seeks to promote his preferred candidate by paying voters to raise their ranking. Classical models of shift bribery assume voters act independently, over…
Universal Solvability for Robot Motion Planning on Graphs
Anubhav Dhar, Pranav Nyati, Tanishq Prasad +2
We study the Universal Solvability of Robot Motion Planning on Graphs (USolR) problem: given an undirected graph and robots, determine whether any arbitrary config…
Minimizing Envy and Maximizing Happiness in Graphical House Allocation
Anubhav Dhar, Ashlesha Hota, Palash Dey +1
We study the house allocation problem in a setting where agents are connected by a graph representing friendships. In this model, two agents can only envy each other if they are ne…
Knapsack on Graphs with Relaxed Neighborhood Constraints
Palash Dey, Ashlesha Hota, Sudeshna Kolay
In the knapsack problems with neighborhood constraints that were studied before, the input is a graph on a set of items, each item h…
Knapsack with Vertex Cover, Set Cover, and Hitting Set
Palash Dey, Ashlesha Hota, Sudeshna Kolay +1
Given an undirected graph , with vertex weights , vertex values , a knapsack size , an…
