Online Large-Scale Taxi Assignment: Optimization and Learning

open access: yesFindings, 2023
We propose a solution method for online vehicle routing, which integrates a machine learning routine to improve tours’ quality. Our optimization model is based on the Bertsimas et al. (2019) re-optimization approach.

High order iterative methods for decomposition‐coordination problems

open access: yesTechnological and Economic Development of Economy, 2006
Many real‐life optimization problems are of the multiobjective type and highdimensional. Possibilities for solving large scale optimization problems on a computer network or multiprocessor computer using a multi‐level approach are studied.

Large-scale recommendation for portfolio optimization [PDF]

open access: yesProceedings of the 12th ACM Conference on Recommender Systems, 2018
Individual investors are now massively using online brokers to trade stocks with convenient interfaces and low fees, albeit losing the advice and personalization traditionally provided by full-service brokers. We frame the problem faced by online brokers of replicating this level of service in a low-cost and automated manner for a very large number of ...

An Entropy-Assisted Particle Swarm Optimizer for Large-Scale Optimization Problem

open access: yesMathematics, 2019
Diversity maintenance is crucial for particle swarm optimizer’s (PSO) performance. However, the update mechanism for particles in the conventional PSO is poor in the performance of diversity maintenance, which usually results in a premature ...
