In this paper, we present two integer linear programming (ILP) formulations to find the most parsimonious phylogenetic tree from a set of binary variation data. One method uses a flow-based ...

Abstract: This paper describes experiences with mixed integer linear programming (MILP) based approaches on the short-term hydro scheduling (STHS) function. The STHS is used to determine the optimal ...

For this purpose, a mixed-integer linear programming (MILP) problem is formulated, where time-dependent binary variables are introduced for describing the switches of the treatment stages. While ...

This paper considers a new canonical duality theory for solving mixed integer quadratic programming problem. It shows that this well-known NP-hard problem can be converted into concave maximization ...

These three definitions were modeled in the AMPL programming language and then solved using the IBM CPLEX solver for two simple examples and a collection of generated data for different combinations ...

The chemical industry is making significant investments in clean energy technologies, such as green hydrogen, carbon capture and storage, electric heating, and electrochemical processes to reduce ...

Torex Semiconductor has created a nano-power dc-dc converter that can occupy only 7.7 x 3.1mm with all external capacitors – the necessary inductor is inside the device package. Called XCL108 and ...

Warner Bros Discovery is close to spinning off its linear channels into a separate business, according to CNBC contributor David Faber. Speaking on CNBC’s Squawk on the Street, Faber said he had ...

To address this issue, the research team proposed a Mixed Integer Programming (MIP) model. It transformed the original bilevel optimization problem into a single-level one, where discrete component ...
