A solution to P vs NP could unlock countless computational problems—or keep them forever out of reach. 1. On Monday, July 19, 2021, in the middle of another strange pandemic summer, a leading computer ...

In computational complexity theory, P and NP are two classes of problems. P is the class of decision problems that a deterministic Turing machine can solve in polynomial time. In useful terms, any ...

The axiomatic treatment of the computational complexity of partial recursive functions initiated by Blum is extended to relatively computable functions (as computed, for example, by Turing machines ...

The aim of this paper is to introduce to the linguistic community some preliminary findings in the area of text planning which I hope will serve to lay the foundations of a computational theory of ...

Researchers at the University of Chicago have created the first usable computational model of the entire virus responsible for COVID-19—and they are making this model widely available to help advance ...

Chemists use density functional theory (DFT) to accurately approximate the exact properties—like free energies—of molecules or materials in a reasonable amount of time. The method is widely used even ...

Quantum researchers in the twenty-first century are part of an international network that requires a great deal of interaction and communication. Around one hundred publications on the topic are ...

The European robin and other birds know where to migrate by sensing the direction of the Earth's magnetic field. Researchers have recently attributed this ability to a chemical reaction that takes ...
