[sage-devel] Closest Vector not in Lattice

2020-06-08 Thread Taylor Huang
It seems to be a bug. As shown in the figure, the computed closest vector is not in the lattice. For copy-paste convenience, see the following. from sage.modules.free_module_integer import IntegerLattice L = Matrix(ZZ,[[20957228, -4966110],[ 9411844, 19625639]]) L = IntegerLattice(L) targ = Matrix
