I will give an overview of our recent results on leveraging integer programming solvers to solve query optimization instances within seconds where traditional optimizers would need weeks of optimization time.
The multivariate method helps to reduce optimization time and improve analytical throughput.
Indeed, small differences may imply large differences in the optimization time.
When applied to overall process optimization, the optimization time is considerably reduced without penalizing the overall power plant model quality.
The presented parameter selection scheme compared to extensive optimization achieves 90% goodness in results with only 5% optimization time, which helps large-scale architecture exploration where optimization time is important.
In this algorithm, some factors have been defined by which the relation between the optimization time and these factors have been calculated, both experimentally and mathematically and the appropriate values of these factors are obtained to reduce the optimization time.
It also possesses advantages of simplicity in process, less reliability on initial model, less optimization time, and good versatility.
Simulated annealing is found better than other algorithms in terms of both optimization time and the result.
Surrogate-assisted evolutionary optimization has proved to be effective in reducing optimization time, as surrogates, or meta-models can approximate expensive fitness functions in the optimization run.
Current Research and Scholarly InterestsResearch interests include clinical trial design, cancer biostatistics, survival analysis, adaptation and sequential experimentation, change-point detection and segmentation, stochastic optimization, time series and inference on stochastic processes, hidden Markov models and genomic applications.
