WebThe master method is a formula for solving recurrence relations of the form: T (n) = aT (n/b) + f (n), where, n = size of input a = number of subproblems in the recursion n/b = size of … Okay, so in algorithm analysis, a recurrence relation is a function relating the amount of work needed to solve a problem of size n to that needed to solve smaller problems (this is closely related to its meaning in math). For example, consider a Fibonacci function below: Fib (a) { if (a==1 a==0) return 1; return Fib (a-1) + Fib (a-2); }
