A major advance reveals deep connections between the classes of problems that computers can — and can’t — possibly do. At first glance, the big news coming out of this summer’s conference on the ...

Computability theory establishes which problems can in principle be solved by mechanical procedures, formalised by the Turing machine model and its equivalents. It draws a firm boundary between ...

Computational complexity theory examines the intrinsic difficulty of algorithmic problems by classifying them into hierarchies according to the resources—typically time and space—required for their ...

Early on in the study of quantum computers, computer scientists posed a question whose answer, they knew, would reveal something deep about the power of these futuristic machines. Twenty-five years ...

Alberta is launching the first phase of its plan to address class size and complexity across schools as new data confirms concerns teachers have raised over the past year. The province will allocate ...

The Alberta government is creating a cabinet committee to study class sizes and classroom complexity in the province’s public education system, tasked with advising on policy and how resources should ...
