Big O notation is a mathematical notation that describes the limiting behavior of a function when the argument tends towards a particular value or infinity Big O is a member of a family of notations invented by Paul Bachmann, Edmund Landau, and others, collectively called Bachmann–Landau notation or asymptotic notation In computer science, big O notation is used to classifyNHO, OHO, and CHO hydrogen bonds in proteinligand complexes strong and weak interactions in molecular recognitionO(nc) polynomial O(cn) exponential Note that O(nc) and O(cn) are very different The latter grows much, much faster, no matter how big the constant c is A function that grows faster than any power of n is called superpolynomial One that grows slower than an exponential function of Di A A Thy O Thyyy I I I I D N O O O O O O U U U U Y Th Ss A A A A A A Ae C E E E E I I I I D N O O O O O n y c h o m y c o s i s
