Complexity theory remains one of the great unsolved mathematical puzzles. Kenneth Regan is trying to figure it out.

Part of “Complexity Theory,” a column on the tangled questions of our technological age. “Addressing algorithmic bias is like hygiene,” she told me. “You don’t brush once, you don’t ...

A new theory could bring a way to make quantum algorithm development less of an accidental process, say scientists.

Computer Scientists Discover Limits of Major Research Algorithm The most widely used technique for finding the largest or smallest values of a math function turns out to be a fundamentally difficult ...

Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time. This means that the increasing complexity of the graphs increased the algorithm's running time ...

Welcome to the website of the CS theory group at CU Boulder! Our faculty and students research all aspects of theoretical computer science, from core areas such as algorithms, complexity, and ...

MicroAlgo integrates the Least Significant Quantum Bit (LSQb) algorithm for quantum images with other related theories, such as quantum information theory and cryptography, to further expand its ...

What if we start a new conversation on complexity, engaging a completely different crowd - hands-on practitioners, the problem solvers, the tinkerers - and approach that conversation in another way?
