The worst-case time complexity of any exact algorithm for the Euclidean or rectilinear minimum-weight perfect matching problem, which takes as input the list of coordinates of n points in R k, is shown to be bo

Low complexity algorithms in knot theoryKnot genusalternating knotcomplexityLogspaceAgol, Haas and Thurston showed that the problem of determining a bound on the genus of a knot in a 3-manifold, is NP-complete. This shows that (unless P = NP) the genus problem has high computational complexity...
Big O notation cares about the worst-case scenario. E.g., when you want to sort and elements in the array are in reverse order for some sorting algorithms. For instance, if you have a function that takes an array as an input, if you increase the number of elements in the collection,...

Their behavior revealed evidence of combinatorial reasoning—when low-complexity algorithms that consider items one at a time provided optimal solutions, the animals adopted low-complexity reasoning strategies. When greater computational resources were required, the animals approximated high-complexity ...
Time Complexity of Algorithms • If running time T(n) is O(f(n)) then the function f measures time complexity –Polynomial algorithms: T(n) is O(n k ); k = const –Exponential algorithm: otherwise • Intractable problem: if no polynomial algorithm ...
