The springs create a controlled, non-linear stiffness profile that lengthens the time over which force is distributed, reducing the risk of component failure. The design focuses on minimizing size and ...

Welcome back to college football in 2025. If you can believe it, I’ve been writing this graphing column for coming into my 10th year now. Scream emoji. Old man emoji. Some of you will also remember ...

We formulate this problem as a nonlinear Generalized Disjunctive Program (GDP), which, following transformation, results in a large-scale mixed-integer nonlinear programming (MINLP) problem. This ...

In contrast, restricting the variables to integer values requires a time increasing exponentially with n, even if the constraints and objective function are linear (known as integer linear programming ...

Benchmark instances modelling the supply chain of a fictive company producing and selling cell phones and accessories of different types. The instances formulate typical mixed-integer linear ...

Today we will try to answer the question ‘ What is the best software for linear programming? ‘ Well, Linear Programming (LP) is, in general, demanding and time-consuming. This is perhaps the reason ...

In this paper, we also present a mathematical programming method in which a mixed integer linear programming model for a minimum backbone grid is proposed. A minimum number of branches and maximum ...

Minimum backbone grid problems compared with selected references. In this paper, we also present a mathematical programming method in which a mixed integer linear programming model for a minimum ...
