Mixed-Integer Convex Nonlinear Optimization with Gradient-Boosted Trees Embedded [PDF]

open access: yes, 2019
Decision trees usefully represent sparse, high dimensional and noisy data. Having learned a function from this data, we may want to thereafter integrate the function into a larger decision-making problem, e.g., for picking the best chemical process ...

MINLP Optimization of Mechanical Structures [PDF]

open access: yesAmerican Journal of Applied Sciences, 2008
We presented optimization of mechanical structures, performed by the Mixed-Integer Nonlinear Programming (MINLP) optimization approach. The MINLP is a combined continuous/discrete optimization technique, where a structural topology and standard/discrete sizes are optimized simultaneously with the continuous variables.
