This puzzle looks like it needs calculus… but you’re not allowed to use it. I explore alternative methods to get the answer only using basic math tools. 8 million inflation refund checks sent out ...

Abstract: The present work proposes a methodology to the problem of short-term economic dispatch of radial and meshed power systems by means of nonlinear programming (NLP). The problem posed will be ...

A new type of computer uses oscillators in special materials to find the most efficient solutions to complex scheduling and routing problems at room temperature. (Nanowerk News) A line of engineering ...

It’s been difficult to find important questions that quantum computers can answer faster than classical machines, but a new algorithm appears to do it for some critical optimization tasks. For ...

We all know that calculus courses such as 18.01 and 18.02 are univariate and vector calculus, respectively. Modern applications such as machine learning and large-scale optimization require the next ...

I have been trying to set up and run ONION geometry-optimization calcs, and have been running into some problems. If I run an open-shell system through xTB, it ignores my attempts to specify the ...

In the late 19th century, Karl Weierstrass invented a fractal-like function that was decried as nothing less than a “deplorable evil.” In time, it would transform the foundations of mathematics.

ABSTRACT: This paper first comprehensively combs and analyzes the different operation modes of China’s new energy vehicle mobile charging service industry through literature reading, enterprise ...
