Coach Reservation for Groups Requests
Carlos H. Cardonha, Arvind U. Raghunathan
Passenger transportation is a core aspect of a railway company's business, with ticket sales playing a central role in generating revenue. Profitable operations in this context rel…
The Sensitivity of the U.S. Presidential Election to Coordinated Voter Relocation
Carlos Cardonha, David Bergman, Andre Cire +2
U.S. presidential elections are decided by the Electoral College, established in 1789, and designed to mitigate potential risks arising from the collusion of large groups of citize…
The Madness of Multiple Entries in March Madness
Jeff Decary, David Bergman, Carlos Cardonha +2
This paper explores multi-entry strategies for betting pools related to single-elimination tournaments. In such betting pools, participants select winners of games, and their respe…
Cardinality-Constrained Continuous Knapsack Problem with Concave Piecewise-Linear Utilities
Miao Bai, Carlos Cardonha
We study an extension of the cardinality-constrained knapsack problem wherein each item has a concave piecewise linear utility structure (CCKP), which is motivated by applications…
Recursive McCormick Linearization of Multilinear Programs
Arvind U Raghunathan, Carlos Cardonha, David Bergman +1
Linear programming (LP) relaxations are widely employed in exact solution methods for multilinear programs (MLP). One example is the family of Recursive McCormick Linearization (RM…
Optimizing the expected maximum of two linear functions defined on a multivariate Gaussian distribution
David Bergman, Carlos Cardonha, Jason Imbrogno +1
We study stochastic optimization problems with objective function given by the expectation of the maximum of two linear functions defined on the component random variables of a mul…
On Approximate Sequencing Policies for Linear Storage Devices
Carlos H. Cardonha, Andre A. Cire, Lucas C. Villa Real
This paper investigates sequencing policies for file reading requests in linear storage devices, such as magnetic tapes. Tapes are the technology of choice for long-term storage in…
Optimizing over an ensemble of neural networks
Keliang Wang, Leonardo Lozano, Carlos Cardonha +1
We study optimization problems where the objective function is modeled through feedforward neural networks with rectified linear unit (ReLU) activation. Recent literature has explo…
Binary Decision Diagrams for Bin Packing with Minimum Color Fragmentation
David Bergman, Carlos Cardonha, Saharnaz Mehrani
Bin Packing with Minimum Color Fragmentation (BPMCF) is an extension of the Bin Packing Problem in which each item has a size and a color and the goal is to minimize the sum of the…
Theoretical and Practical Aspects of the Linear Tape Scheduling Problem
Carlos Cardonha, Lucas C. Villa Real
Magnetic tapes have been playing a key role as means for storage of digital data for decades, and their unsurpassed cost-effectiveness still make them the technology of choice in s…
Network Models for Multiobjective Discrete Optimization
David Bergman, Merve Bodur, Carlos Cardonha +1
This paper provides a novel framework for solving multiobjective discrete optimization problems with an arbitrary number of objectives. Our framework formulates these problems as n…
Modeling Epistemological Principles for Bias Mitigation in AI Systems: An Illustration in Hiring Decisions
Marisa Vasconcelos, Carlos Cardonha, Bernardo Gonçalves
Artificial Intelligence (AI) has been used extensively in automatic decision making in a broad variety of scenarios, ranging from credit ratings for loans to recommendations of mov…
On the Minimum Chordal Completion Polytope
David Bergman, Carlos H. Cardonha, Andre A. Cire +1
A graph is chordal if every cycle of length at least four contains a chord, that is, an edge connecting two nonconsecutive vertices of the cycle. Several classical applications in…
Patience-aware Scheduling for Cloud Services: Freeing Users from the Chains of Boredom
Carlos Cardonha, Marcos D. Assunção, Marco A. S. Netto +2
Scheduling of service requests in Cloud computing has traditionally focused on the reduction of pre-service wait, generally termed as waiting time. Under certain conditions such as…
