Abstract: Descriptive Complexity has been very successful in characterizing complexity classes of decision problems in terms of the properties definable in some logics. However, descriptive complexity ...

For decades, computer scientists have compared the fundamental difficulty of solving various tasks, such as factoring a number or finding the most efficient route for a traveling salesperson. Along ...

Add a way for users to say e.g. "linear or logarithmic complexity" in a complexity annotation. One way to do this may be to overload the | operator: TimeComplexity(cplx.linear | cplx.logarithmic).

Understanding time complexity becomes easier when we relate it to familiar situations. Below are common complexity classes explained using simple analogies and real-life comparisons. Finding a friend ...
