Algorithm Selection Using Deep Learning

Conference Proceeding
Alissa, M., Sim, K., & Hart, E. (2019)
Algorithm Selection Using Deep Learning. In GECCO '19 Proceedings of the Genetic and Evolutionary Computation Conference, (198-206). https://doi.org/10.1145/3321707.3321845
We propose a novel technique for algorithm-selection which adopts a deep-learning approach, specifically a Recurrent-Neural Network with Long-Short-Term-Memory (RNN-LSTM). In ...

A hyper-heuristic ensemble method for static job-shop scheduling.

Journal Article
Hart, E., & Sim, K. (2016)
A hyper-heuristic ensemble method for static job-shop scheduling. Evolutionary Computation, 24(4), 609-635. https://doi.org/10.1162/EVCO_a_00183
