The Theory of Computation explores the fundamental capabilities and limits of computing processes. It encompasses models such as finite automata, push-down machines and Turing machines, which ...

"Many computational machines, when viewed as dynamical systems, have this property where if you jump from one state to another you really can't go back to the original state in just one step," says ...

In conventional computing, we can draw a clean line between software and hardware. In brains, there is no such separation of different scales. In the brain, everything influences everything else, from ...

For decades, philosophers and physicists alike have speculated that our entire existence might be nothing more than an advanced simulation. But new research from the University of British Columbia ...

Computer Scientists are the broad group of individuals who utilize their skills to perform, develop, and improve computation. Computation is all around us: On our laptops, in our phones, running web ...

You may think of physics as a way to explain the behaviors of things like black holes, colliding particles, falling apples, and quantum computers. But a small group physicists today is working on a ...

Theory of Computation offers a rigorous mathematical framework that underpins our understanding of what can be computed and how efficiently these computations may be performed. It encompasses ...
