- GJ21.short_vectors_simple(beta, d, N=None, B=None, preprocess=True)#
Cost of outputting many somewhat short vectors.
The output of this function is a tuple of four values:
ρ is a scaling factor. The output vectors are expected to be longer than the shortest vector expected from an SVP oracle by this factor.
c is the cost of outputting N vectors
N the number of vectors output, which may be larger than the value put in for N.
β’ the cost parameter associated with sampling, here: β
This naive baseline implementation uses rerandomize+BKZ.
beta – Cost parameter (≈ SVP dimension).
d – Lattice dimension.
N – Number of vectors requested.
B – Bit-size of entries.
preprocess – This option is ignore.
