General

  • The NL reader API is now stable
  • AMPL Solver Library version 20150318: changelog
  • New C API for a subset of ASL functions contributed by Dominique Orban (#36)
  • Improved type safety of expression API (#35)
  • Added AMPL_LIBRARY_DIR CMake variable which specifies a directory to install AMPL function libraries relative to ${CMAKE_INSTALL_PREFIX} (#32)
  • .mex files are now installed in the same directory as shared libraries (#27, #32)
  • Fixed detection of floating-point arithmetic on non-x86 architectures (#25)

LocalSolver

  • Updated to version 5.0

  • The normal verbosity is now mapped to LocalSolver verbosity=1 and terse to custom output

  • Added support for piecewise-linear terms:

    var x;
minimize o: <<0; -1, 1>> x;
option pl_linearize 0;
option solver localsolver;
solve;

    The new option pl_bigm controls the artificial bound used for unbounded variables in piecewise-linear terms.

  • Objective bound can now be specified with the bound suffix:

    suffix bound;
minimize o: sum{i in 1..NumOrders} WastedSteel[i] suffix bound 0;

Gecode

  • Updated to version 4.4.0: changes

  • Clp 1.16.4
  • Cbc 2.9.3
  • Ipopt 3.12.1
  • Bonmin 1.8.1
  • Couenne 0.5.3
