Explore zero-one integer programming, a key method in logical problem-solving, using binary choices for optimal decisions in finance, production, and more.
Try this ancient multiplication trick—halves and doubles, also called Egyptian or Russian math—where you repeatedly halve one ...
Abstract: Random number generation is essential for applications in simulation, numerical analysis, and data encryption. The ubiquitous presence of system-on-chip (SoC) field-programmable gate array ...
From machine learning to voting, the workings of the world demand randomisation, but true sources of randomness are ...
Abstract: Sampled-data control of heterogeneous fractional-order (FO) multiagent systems (MASs) under nonidentical denial-of-service (DoS) attacks and time delays is investigated in this study. Based ...
A paradox sits in the middle of the energy transition math. If nearly 10 trillion dollars buys only a 7 percent reduction in fossil fuels’ share of demand, what does 304 trillion buy? The number, ...
A tiny black hole zipping through your body sounds like the kind of death dreamed up by a pulp-era sci-fi writer. Which, fittingly enough, it was. In 1974, Larry Niven imagined a murder carried out by ...
