██ ■ RELEASE iNFO: ██
▒ ▒
The recently released LINGO 8.0 includes a number of
significant enhancements and new features. Several of the
enhancements focus on finding better solutions to tough
nonlinear problems. This release also includes a number of
modifications to significantly improve performance on many
linear and integer models.
New Global Solver
We are very excited about the new global solver added as part
of this release. The global solver combines a series of range
bounding (e.g., interval analysis and convex analysis) and
range reduction techniques (e.g., linear programming and
constraint propagation) within a branch-and-bound framework
to find global solutions to non-convex Nonlinear Programs
(NLPs). Rather than stopping after the first local optimum is
found, the global solver will search until the global optimum
is confirmed. The nonlinear and global license options are
required in order to utilize the global optimization
capabilities with LINGO.
Multistart Capability
When limited time makes searching for the global optimum
prohibitive, the new Multistart feature can be a powerful
tool for finding good solutions more quickly. This feature
intelligently generates a set of candidate starting points in
the solution space of NLPs and mixed integer NLPs. Then, the
native NLP solver selects a subset of these candidate
solutions to initialize a series of local optimization. For
non-convex NLP models, the quality of the solution returned
by the multistart solver will be superior to that of the
general nonlinear solver. A user adjustable parameter
controls the maximum number of multistarts to be performed.
The nonlinear and global license options are required in
order to utilize the multistart feature with LINGO.
Quadratic Recognition and Solver
Quadratic Programming (QP) models are a common class of
nonlinear model that is encountered in applications such as
financial portfolio analysis. The new QP recognition tool in
this release of LINGO is a useful algebraic pre-processor
that automatically determines if an arbitrary NLP is actually
a quadratic model. QP models may then be passed to the faster
quadratic solver, which is available as part of the barrier
solver option.
Faster Dual Solver
The improved Dual Simplex solver in LINGO 8.0 delivers
substantially better performance. On broad classes of
problems, the new solver can provide speed improvements up to
300%. The solver is also even more robust due to improved
handling of degenerate and numerically unstable models.
Improved Integer Solver
The new integer solver benefits from a number of enhancements
that boost performance on many classes of problems. A
partial list of new features include:
More advanced probing/pre-solvingùincluding lifting clique
Special pre-solving of rows containing all binary variables
Additional cut generation
Faster cut generation
Improved rounding heuristic
New enumeration solver for pure binary models
Many new user controllable parameters
Improved reduced cost fixing and bound tightening within
the tree
Improved performance on mixed integer QPs
Linearization Capability
The new Linearization capabilities of LINGO can dramatically
improve performance on models with common nonsmooth
functions. Linearization is a comprehensive reformulation
tool that automatically converts many non-smooth functions
and operators (e.g., @MAX and @ABS) to a series of linear,
mathematically equivalent expressions. Many non-smooth models
may be entirely linearized. This allows the linear solver to
quickly find a global solution to what would have otherwise been
an intractable problem.
Infeasible and Unbounded Analytical Tools
LINGO 8.0 includes a new set of tools that allow you to
pinpoint what is causing a model to be infeasible or
unbounded. A small portion of the original model is isolated
as the source of the problem. This allows you to focus your
attention on a subsection of the model in search of
formulation or data entry errors. On infeasible models, an
irreducibly inconsistent set of constraints (IIS) is reported. On
unbounded models, an irreducibly unbounded set of columns (IUS)
is reported.
New Decomposition Feature
Many large scale linear and mixed integer problems have
constraint matrices that are totally decomposable into a
series of independent block structures. A new feature in
LINGO 8.0 tells the solver to check if a model can be broken
into smaller independent models. If total decomposition is
possible, it will solve the independent problems sequentially
and report a solution for the original model. This may result
in dramatic speed improvements.
