WebJul 25, 2024 · If the complexity of an algorithm is expressed as O (p(n)) where p(n) is some polynomial of n, then the algorithm is said to be a polynomial time algorithm. Generally, polynomial time algorithms are tractable. Any algorithm with a time complexity that cannot be bounded by such bound then this is known as non - polynomial algorithms. WebThe converse to the last statement also explains part of the interest in ${\sf NP}$-completeness among algorithm designers: if ${\sf P} \neq {\sf NP}$ (as is widely believed), then it means that no problem that corresponds to an ${\sf NP}$-hard language can be solved by any polynomial-time algorithm.
