This list will be following
julia-dev,
julia-users, and
julia-stats (among others) in moving to
discourse.julialang.org. See the linked discussions for further background.
To continue following discussions on optimization in Julia, you should create an account on discourse and "watch" the "Optimization (Mathematical)" category. We will not be automatically migrating subscribers.
I will leave this topic briefly open for discussion, but the intention is to make the julia-opt group read-only in the near future, accessible for historical interest.
