Phillippe Samer's Problem Solving Experience:

  1. - I co-founded In OPTIMA Consultoria, a business consulting company specialized in optimization and operations research technologies. I am particularly proud of serving the major mining company in Brazil in two projects. In the last one, I developed formulations in integer linear programming for a mixture/blending problem, with implementations in Python using the Gurobi solver. I have also developed a series of models for a nurse scheduling application in a Brazilian hospital, using CBC since the project required using free software only.
  2. - Given a fixed 6-month contract as visiting Assistant Professor in Norway to do research on a combinatorial optimization problem arising in maritime logistics, I developed a technique to give solution bounds and a matheuristic (heuristic based on mathematical programming) to find near-optimal solutions in greatly reduced computation time. I used the Gurobi solver and python programming. Results include 3 research papers, one of which I presented in Italy on June.
  3. - During my MSc degree, I developed mixed-integer programming formulations and exact decomposition algorithms for a problem in graph theory. The implementation used C++ and the CPLEX solver. The results were described in two journal papers (Optimization Letters and Computational Optimization and Applications) and two conferences (one of which, in Chile, I was awarded a stipend to attend). I have also spent the autumn/winter season of 2013/2014 at Hokkaido University, in Japan. I was honored to be one of 3 students recommended by the consulate general of Japan in Rio de Janeiro for the Monbukagakusho/MEXT Scholarship.
  4. - I am also a Professor (lecturer) in courses on applied mathematics and computer science. For one year (2015) I was Assistant Professor at the Federal Center for Technological Education in Minas Gerais (CEFET-MG, Brazil), teaching Numerical Analysis and Algorithms and Data Structures. Previously, I was also an Assistant Professor at the Catholic University Minas Gerais (PUC-Minas) for one year, teaching Graph Theory, Linear Optimization, and Algorithms and Data Structures.
