Computational Complexity

Explore how mathematics studies the efficiency and difficulty of computational problems.

Some problems are much harder to solve than others.

Computational complexity studies the resources needed for computation.


What This Topic Studies

This section studies:

  • computational difficulty
  • efficiency
  • running time
