scip 1.10.1-1

• Upgrade the bundled solvers to the SCIP Optimization Suite 10.1.0 (released 2026-09-18): SCIP 10.1.0, SoPlex 8.1.0, PaPILO 3.0.2.
• New scip_control() arguments presolve_emphasis and separating_emphasis, taking "default", "aggressive", "fast", or "off" exactly like the existing heuristics_emphasis. They map to SCIP’s SCIPsetPresolving() and SCIPsetSeparating() meta-settings, which adjust whole families of parameters at once and cannot be reproduced through individual parameters (#2).
• New scip_control() argument emphasis exposing SCIP’s global parameter profiles (SCIPsetEmphasis()): "feasibility", "optimality", "hardlp", "numerics", "easycip", "cpsolver", "counter", "phasefeas", "phaseimprove", "phaseproof", "benchmark". All emphasis settings are applied before individual parameters, so a native parameter passed via ... still wins.
• Installing from a source checkout is now more efficient.

scip 1.10.0-4

• Fix compilation with LLVM 23’s libc++, reported by CRAN’s r-devel-linux-x86_64-fedora-clang check. libc++ 23 dropped many transitive includes in all language modes, exposing three headers that relied on them: <istream> in SoPlex’s basevectors.h and mpsinput.cpp, and <cstdlib> in SCIP’s multiprecision.hpp. Because basevectors.h is reached from soplex.h, the first of these broke every translation unit including SoPlex. No user-visible change.

scip 1.10.0-3

• 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 §1.2.1.1.
• 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.
