estimator.prob.drop

estimator.prob.drop(n, h, k, fail=0, rotations=False)

Probability that k randomly sampled components have fail non-zero components amongst them.

Parameters:

• n – LWE dimension n > 0

• h – number of non-zero components

• k – number of components to ignore

• fail – we tolerate fail number of non-zero components amongst the k ignored components

• rotations – consider rotations of the basis to exploit ring structure (NTRU only)
