    Research in Progress

    "A Compact Formulation for Robust Optimization versus A Bertsimas and Sim Heuristic Method" (On-Going)
    Location problems arise in many applications and have received significant attention from the OR community. Optimization under uncertainty and in particular robust optimization is relevant in location applications when there incomplete information. In this papers, we compare two very different strategies for robust optimization in a family of location problems: a compact formulation that seeks to achieve an optimal solution in a holistic formulation, and a sequential and fractional formulation within a heuristic.

    "Agent-based Modeling of Dependence Networks" (On-Going)
    We live in an interconnected world where agents depend on each other to achieve their personal and group goals. We model this inter-dependency using agent-based simulation and test various hypothesis regarding rules of engagement, dissipation of information in the network, discrepancy between reality and beliefs and the updating and correction of beliefs. This information can inform the design of social platforms as the implications of choice characteristics are better understood.

    "Heuristics for the robust prize-collecting steiner tree problem" (On-Going)
    We propose a heuristic based on Bertsimas-Sim approach to the prize-collecting steiner tree problem. In the prize-collecting steiner tree problem, we are given a set of customers with potential gains of revenue and the set of edges with fixed installation costs. The goal is to decide which customers to connect to a given root node so that the sum of edge costs plus the node revenues for the nodes that are left out from the solution is minimized. We assume that the revenue and cost have interval uncertainty and propose a modified Bertsimas-Sim heuristic.
