Thus, the time complexity is oppressed by the cost of f(n). If the cost of solving the subproblems at each level decreases by a certain factor, the value of f(n) will become polynomially larger than n log b a.Thus, the time complexity will be f(n) times the total number of levels ie. If the cost of solving the sub-problem at each level is nearly equal, then the value of f(n) will be n log b a.Thus, the time complexity is oppressed by the cost of the last level ie. If the cost of solving the sub-problems at each level increases by a certain factor, the value of f(n) will become polynomially smaller than n log b a.If f(n) = Ω(n log b a+ϵ), then T(n) = Θ(f(n)).Įach of the above conditions can be interpreted as: If f(n) = Θ(n log b a), then T(n) = Θ(n log b a * log n).ģ. Where, T(n) has the following asymptotic bounds:ġ. If a ≥ 1 and b > 1 are constants and f(n) is an asymptotically positive function, then the time complexity of a recursive relation is given by The master theorem is used in calculating the time complexity of recurrence relations ( divide and conquer algorithms) in a simple and quick way. Here, a ≥ 1 and b > 1 are constants, and f(n) is an asymptotically positive function.Īn asymptotically positive function means that for a sufficiently large value of n, we have f(n) > 0. Which includes the cost of dividing the problem and

All subproblems are assumedį(n) = cost of the work done outside the recursive call, The master method is a formula for solving recurrence relations of the form:Ī = number of subproblems in the recursion Spanning all disciplines and regions, Web of Science Core Collection is at the heart of the Web of Science platform.
