6 years ago Hi @stumarcus576, those actually aren't errors, just warnings about deprecated syntax. Your getting meaningless answers because you haven't called solve on your model.
I'll leave this open until I tag a new version with the deprecation warnings fixed.
I run macOS Sierra version 10.12.6 and Julia 0.6.2. I am trying to run the Julia JuMP program below using PiecewiseLinearOpt and get the errors below.
using JuMP, PiecewiseLinearOpt m = Model() @variable(m, x) @variable(m, y)
z = piecewiselinear(m, x, y, 0:0.1:1, 0:0.1:1, (u,v) -> exp(u+v)) @objective(m, Min, z)
println("Objective value: ", getobjectivevalue(m)) println("x = ", getvalue(x)) println("y = ", getvalue(y))
julia pw_test.jl
