I’m having some issues with Ipopt not finding a solution with a script I’m updating to Julia 1.1 / JuMP 0.19 from a functioning one on Julia 0.64 / JuMP 0.18.
Unsure exactly where the problem is, so I’ve put the script in a gist so you can see the changes I’ve made.
Functioning version (Julia 0.64, JuMP 0.18)
Runtime on my machine
5.514864 seconds (5.72 M allocations: 172.761 MiB, 2.19% gc time)
Attempt at update to Julia 1.1, JuMP 0.19
On the third
optimize!, this one seems to hit a convex region and just spools forever.
Diff between the two versions
The changes here, as far as I can tell, are the only ones that need to be made. Arrays need to conform to the v1.1 syntax, and then the new JuMP syntax is also altered, although nothing else is done.
Is there something obvious that I’ve missed? Are there some pointers you could give me to help solve this problem?
