-Subject: [PATCH] fix(util/utils): duplicate zeros in filter_operator
-
-The explicit zeros added to A to match C's nonzeros can be redundant
-with the existing entries in A. These duplicate entries are acted on
-independently by amg_core.satisfy_constraints_helper, causing the
-update to effectively happen multiple times when duplicate entries in
-sparse arrays are added together according to scipy's semantics.
