GPU-accelerated wind farm layout search with a distilled endogenous wake model (EndoWake)
Martina Fischetti, Matteo Fischetti
Wind farm layout optimization decides where to place turbines to maximize annual energy production, and wake effects decide how much of that energy is produced. Accurate wake model…
EndoWake: Modeling Wind by Linear Programming for Wind Farm Layout Optimization
Martina Fischetti, Matteo Fischetti
The Wind Farm Layout Optimization problem consists of placing a given number of turbines within a given area so as to maximize energy production. One of its main challenges is the…
Minibatch persistency, eight years later: what batch reuse costs in steps and joules, and what it saves in data
Matteo Fischetti
Minibatch persistency reuses data instead of reading it: rather than drawing a fresh minibatch at every optimizer step, it takes K consecutive steps on the same one. Absorbed into…
Revisiting local branching with a machine learning lens
Defeng Liu, Matteo Fischetti, Andrea Lodi
Finding high-quality solutions to mixed-integer linear programming problems (MILPs) is of great importance for many practical applications. In this respect, the refinement heuristi…
Finding First and Most-Beautiful Queens by Integer Programming
Matteo Fischetti, Domenico Salvagnin
The n-queens puzzle is a well-known combinatorial problem that requires to place n queens on an n x n chessboard so that no two queens can attack each other. Since the 19th century…
Embedded hyper-parameter tuning by Simulated Annealing
Matteo Fischetti, Matteo Stringher
We propose a new metaheuristic training scheme that combines Stochastic Gradient Descent (SGD) and Discrete Optimization in an unconventional way. Our idea is to define a discrete…
