Sometimes it would be nice to help the solver by supplying the first guess manually

(btw again this might be better directly in CTs)

In JuMP you just do something like set_start_value(variable_ref, number). See here: https://jump.dev/JuMP.jl/stable/manual/variables/#Start-values. Yep, might be better in CTs to be more general

@stelmo btw is there a good usecase for this? So that I can write a test or so.
