Algorithms and Theory       


Algorithms and Theory - overview

Our dual objective is to pursue basic research on a broad range of theoretical topics and to impact real-world issues by applying our expertise to solving problems for IBM and its clients.

We do basic research in a number of areas of theoretical computer science, including approximation algorithms, combinatorics, complexity theory, computational geometry, distributed systems, learning theory, online algorithms, cryptography and quantum computing.

IBM researchers have access to an extensive array of challenging problems that motivate innovative solutions and, at the same time, constantly push the theoretical state-of-the-art with the development of new algorithms and new optimization techniques. We provide innovative, custom solutions to business and industrial problems that are at the boundaries of what can be solved today.
