CaNNOLeS - Constrained and NoNlinear Optimizer of Least Squares

CaNNOLeS is a solver for equality-constrained nonlinear least-squares problems, i.e., optimization problems of the form

min ¹/₂‖F(x)‖²      s. to     c(x) = 0.

It uses other JuliaSmoothOptimizers packages for development. In particular, NLPModels.jl is used for defining the problem, and SolverCore for the output. It also uses HSL.jl's MA57 as main solver, but you can pass linsolve=:ldlfactorizations to use LDLFactorizations.jl.

If you use CaNNOLeS.jl in your work, please cite using the format given in CITATION.cff.

Installation

Follow HSL.jl's MA57 installation if possible. Otherwise LDLFactorizations.jl will be used.
pkg> add CaNNOLeS

Examples

```julia using CaNNOLeS, ADNLPModels

Rosenbrock

nls = ADNLSModel(x -> [x[1] - 1; 10 * (x[2] - x[1]^2)], [-1.2; 1.0], 2) stats = cannoles(nls)

Constrained

nls = ADNLSModel( x -> [x[1] - 1; 10 * (x[2] - x[1]^2)], [-1.2; 1.0], 2, x -> [x[1] * x[2] - 1], [0.0], [0.0], ) stats = cannoles(nls) ```
