Upgrade to SCIP 10.0.2, SoPlex 8.0.2, PaPILO 3.0.0.
Enable OpenMP thread pool interface (TPI=omp) when the platform
supports it, giving SCIP parallel branch-and-bound. Falls back
gracefully to TPI=none when OpenMP is unavailable.
Use SHLIB_OPENMP_CXXFLAGS in both
PKG_CXXFLAGS and PKG_LIBS per R-exts
ยง1.2.1.1.
Drop all tinycthread patches (no longer compiled with TPI=omp/none).
Reduces R-specific patch burden from 14 to 10 across submodules.
scip 1.10.0-1
Switched build system from hand-maintained Makevars.in (472 lines)
to CMake-based build at install time, following the highs R package
pattern.
Solver sources (SCIP, SoPlex) moved from src/ to
inst/ and deleted after compilation when installing from
tarball, reducing installed size from ~258 MB to ~10 MB.
Version now tracks SCIP Optimization Suite (10.0.x).
scip 0.0.2
Initial CRAN submission.
One-shot solver interface (scip_solve) and incremental
model-building API (scip_model, scip_add_var,
scip_add_linear_cons, scip_add_quadratic_cons,
scip_add_sos1_cons, scip_add_sos2_cons,
scip_add_indicator_cons).
Solver control parameters (scip_control).
Sparse matrix support (dgCMatrix, simple_triplet_matrix).
Vignette with LP, MIP, quadratic, and indicator constraint
examples.
Builds on macOS, Linux, and Windows using vendored SCIP 10.0.1 and
SoPlex 8.0.1 sources.
