Web29 mrt. 2024 · It sounds like you're saying that memoization speeds up the recursion in both cases, because prior values are never cached in its absence. Thus withf[x_]:= f[x-1] +1, a call is required to f[x-1], which in turn requires a call to f[x-2], and so on. With memoization, by contrast, such recalculation would not be needed. $\endgroup$ –
