Operations research transforms the scheduling of chilean soccer leagues and south American world cup qualifiers
(INFORMS, 2017)
For the past 12 years, the Chilean Professional Soccer Association (ANFP) hasapplied operations research (OR) techniques to schedule soccer leagues in Chile. Usinginteger programming-based methods, the ANFP decides which ...
A branch and price algorithm for a Stackelberg Security Game
(Elsevier, 2017)
Mixed integer optimization formulations are an attractive alternative to solve Stackelberg Game problems thanks to the efficiency of state of the art mixed integer algorithms. In particular, decomposition algorithms, such ...
A column generation approach to multiscale capacity planning for power-intensive process networks
(Springer New York LLC, 2019)
Due to the high volatility in electricity prices, power-intensive industrial plants often have to frequently shift load in order to remain cost-competitive. Capacity planning is required for assessing the value of additional ...
Identifying web sessions with simulated annealing

Delivery of efficient service through a web site makes it compulsory in the redesigning stage to take into
account the behavior of the users, which can be studied by means of a web log file that partially records
information ...
A New Algorithm for the Open-Pit Mine Production Scheduling Problem
(2012)
For the purpose of production scheduling, open-pit mines are discretized into three-dimensional arrays known as block
models. Production scheduling consists of deciding which blocks should be extracted, when they should ...
