What's new

YALMIP 3 is a major revision compared to earlier versions. The internal machinery of YALMIP has been rewritten, and the main result is the possibility to work with nonlinear expressions. In addition, mixed integer capabilities have been improved, and a number of new solvers have been interfaced.

YALMIP 3 [R20040306]

	Determinant maximization problems can now be solved using any SDP solver.
	Global bilinear programming (beta version, slow and unstable...)
	Extended mixed integer code to include posynomial geometric programming (requires latest MOSEK patches, not tested seriously).
	Least squares assignment in setsdpvar.
	sdpvar can be called with only one argument (simplifies definition of symmetric matrices and scalars).

Fixed bug in internal mixed integer solver (might have caused YALMIP to miss the optimal solution.)

Fixed bug on overloaded >= operator.

Fixed bug on purely binary problems using MOSEK.

Fixed bug in interface to PENBMI (may have caused erroneous solutions in some rare cases).

Fixed various bugs to enable nonlinear objective functions in moment relaxations.

YALMIP does not mean Yet Another LMI Parser any more.

YALMIP now works with LMILAB in MATLAB 5.3.

Various fixes for MATLAB 5.3.

News in Version 3 compared to 2.4

	Polynomial expressions.
	Quadratic objective functions.
	Interfaces to solvers PENSDP, PENBMI, LMILAB, NAG, CDD, OOQP, MOSEK, CPLEX, LINPROG and QUADPROG.
	Added possibility to define KYP-related constraints (kyp) and related interface to the specialized code KYPD.
	Multi-parametric linear and quadratic programming using MPT-Toolbox.
	Integer and binary variables.
	Posynomial geometric programming.
	An internal (wickedly slow) branch-and bound solver for mixed integer conic programs (MILP, MIQP, MISOCP, MISDP).
	Sum-of-squares decompositions.
	Moment-based polynomial programming.
	Simple definition of double-sided constraints (see Linear regression example).
	Plot the feasible set of a constraint.
	Imroved functionality in checkset (previously called checklmi).
	Imroved support for subsref in set (previously called lmi) and sdpvar objects.
	New feature in the option removeequalities in sdpsettings.
	New feature in the option cachesolvers in sdpsettings.
	New feature in the option usex0 in sdpsettings.
	New feature in the option radius in sdpsettings.
	New feature in the option shift in sdpsettings.

	Updated interfaces to new versions of CSDP, DSDP, SDPT3 and GLPK.
	Improved error detection in SeDuMi and GLPK.
