To optimize the operation of a heating, ventilation, and air-conditioning (HVAC) system with advanced techniques such as artificial neural network (ANN), previous studies usually need forecast information in their method. However, inevitably contains errors all time, which degrade performance HVAC operation. Hence, this study, we propose mixed-integer linear programming (MILP)-based imitation l...

This work concerns the maximum capture problem with random utilities, i.e., the problem of seeking to locate new facilities in a competitive market such that the captured demand of users is maximized, assuming that each individual chooses among all available facilities according to a random utility maximization model. The challenge when solving this problem is the nonlinearity of the objective ...

An important advantage of genetic algorithms (GAs) are their ease of use, their wide applicability, and their good performance for a wide range of different problems. GAs are able to find good solutions for many problems even if the problem is complicated and its properties are not well known. In contrast, classical optimization approaches like linear programming or mixed integer linear program...

This paper addresses the solution of a cardinality boolean quadratic programming problem using three different approaches. The first transforms the original problem into six Mixed-Integer Linear Programming (MILP) formulations. The second approach takes one of the MILP formulations and relies on the specific features of an MILP solver, namely using starting incumbents, polishing, and callbacks....

In this paper, we present an improved differential-linear cryptanalysis of the ChaCha stream cipher. Our main contributions are new distinguishers that were able to build thanks following improvements: a) considered a larger search space, including 2-bit differences (besides 1-bit differences) for difference at beginning differential part trail; b) better choice mask between and linear parts; c...
