██ ■ 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. You can download a
limited capacity version from our download page or order a full blown
version from our order page today.
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.
