Julia software for computing projections onto intersections of convex and non-convex constraint sets.

Documentation

• install Julia Operators LIbrary (JOLI)
• then add SetIntersectionProjection:

add https://github.com/slimgroup/SetIntersectionProjection.jl.git

• SetIntersectionProjection also depends on the packages:

  • Parameters
  • Interpolations
  • DistributedArrays
  • SortingAlgorithms
  • FFTW
  • Wavelets

• The examples also use the packages:

  • MAT
  • PyPlot
  • StatsBase

• master branch works with Julia 1.5
• see https://github.com/slimgroup/ConstrainedFWIExamples for some more examples of how to use this package as the projector in combination with other software packages that compute function values and gradients for PDE-constrained optimization.
• The waveform inversion example illustrates how SetIntersectionProjection can work together with other packages in other Julia versions (requires some package installations in Julia 0.6)
• the V06 branch works with Julia 0.6 and is intended only for the waveform inversion example that uses WAVEFORM.jl
