Julia interface to SNOPT (must obtain a licensed copy of SNOPT separately)

snopt.jl's Issues

Integer upper bounds, lower bounds, and starting point

MWE:

function matyas_snopt(x)
    f = 0.26 * (x[1]^2 + x[2]^2) - 0.48 * x[1] * x[2]
    c = []
    fail = false
    return f, c, fail
end
x0 = [5;7]
lb = [-10.0; -10.0]
ub = [10.0; 10.0]
options = []
xopt, fopt, info = snopt(matyas_snopt, x0, lb, ub, options)

Returns ([5, 7], 4.661778256194974e-9, “Finished successfully: optimality conditions satisfied”) when it should return [0.0, 0.0]

Print SNOPT iteration history to terminal?

Hi,

Is there a way to view the SNOPT iteration log directly to the terminal/REPL as it runs? The examples I ran all appear to print these details to an external file.

Large integer return as 'xopt' - SNOPT-7.2.11

I am getting a vector of large integers as the solution of my problem.

xopt, fopt, info = snopt(prob, x0, xl, xu, options)
println(xopt[1])

The result is
4647443604925490822
The number in 'snopt-print.out' is correct.

It works fine for the test problems.

Not enough memory

Line 208 of Snopt.jl has

# working arrays
lencw = 500 + (n+nF)
cw = Array{UInt8}(lencw, 8)
leniw = 500 + 100*(n+nF)
iw = Array{Int32}(leniw)
lenrw = 500 + 200*(n+nF)
rw = Array{Float64}(lenrw)

which all of us in the lab have had to change to:

# working arrays
lencw = 500 + (n+nF)*5
cw = Array{UInt8}(lencw, 8)
leniw = 500 + 100*(n+nF)*5
iw = Array{Int32}(leniw)
lenrw = 500 + 200*(n+nF)*5
rw = Array{Float64}(lenrw)

because it seems to not always have enough memory. I'll push these changes unless Dr. Ning has a different way.

Snopt version

I am trying to use your package but having issues calling functions like openfiles_ etc. Which version of Snopt does this assume ?

Does the package support trial libraries?

I am using Snopt7.7 with a trial license.

The evaluation version only gives a shared library or static library.

Printing Summary at Major and Minor Iterations During Optimization

It would be great to get updates on the status of optimization at major and minor iterations during optimization in the terminal (i.e., the default printing behavior of SNOPT when used directly or through the c-interface). The output files are sufficient but having the ability to observe the status of optimization directly from the terminal is a nice quality of life improvement over files alone.

I did not notice anything in the Snopt.jl source code which explicitly adjusts SNOPT's printing behavior, so I expect this is an issue with the Julia/Fortran interoperability?

P.S. Thank you for developing this package. I look forward to using it.

Are infeasible constraints sometimes ignored?

Hello,
Thank you for making this package open source. I am wondering why infeasible constraints are sometimes ignored in my installation. The following example:

function f(g, df, dg, x, deriv)
    g[1] = 10. + x[1]
    return x[1], false
end

lx = [0.]
ux = [1.]
lg = [0.]
ug = [1.]
x0 = [0.5]

options = Dict(
    "Derivative option" => 0
)
rows = [1]
cols = [1]
xopt, fopt, info, out = snopta(f, x0, lx, ux, lg, ug, rows, cols, options)

returns:

"Finished successfully: optimality conditions satisfied"

I am using Snopt7 on a linux machine. Package build and test run successfully.
Could someone run the code above and tell me if they get the same issue? Any idea how to fix it?

Thank you very much,
Jean

Compiled library location

The Snopt.jl file as is requires some changes in where the Snopt shared library is located. My current setup is just to place the library in usr/local/lib and change all references to it to "libsnopt". This works ok, but I would prefer to work on a clean git branch if at all possible. Assuming the compiled library is located in a fixed location relative to Snopt.jl this shouldn't be hard to implement using the macro @__FILE__. Is there a reason the current implementation is set up the way it is?

Issues Building Package

Hello,

I followed all of the installation steps but get the following error messages when trying to build. I appreciate any feedback you can provide.
