Definition
An algorithm may be analysed in the context of its complexity.

This is typically via measures of run-times using big-$\OO$, or big-$\Omega$, or big-$\Theta$ notation.

Complexity can be through 3 main types of analysis:


 * 1) Average-Case Analysis, using a distribution of cases to find an average case of the algorithm run-time for analysis
 * 2) Best-Case Analysis, using the best possible problem instance of the algorithm for analysis
 * 3) Worst-Case Analysis,using the worst possible problem instance of the algorithm for analysis
