Performed narrowing of the following TRS rules:

if(false, x, y) → pr(x, y) [1]
if(true, x, y) → false [1]
pr(x, s(s(y))) → if(eq(x, times(div(x, s(s(y))), s(s(y)))), x, s(y)) [2]
pr(x, s(0)) → true [1]

And obtained the following new TRS rules:

if(false, x, y) → pr(x, y) [1]
if(true, x, y) → false [1]
pr(x, s(s(y))) → if(eq(x, times(quot(x, s(s(y)), s(s(y))), s(s(y)))), x, s(y)) [3]
pr(0, s(s(y))) → if(eq(0, times(0, s(s(y)))), 0, s(y)) [3]
pr(x, s(0)) → true [1]

Which were then size abstracted to RNTS rules to simplify the current SCC:
