Company Background, Products and Services

Introduction

Pintér Consulting Services (PCS) is an incorporated Canadian company, in continuous operation since 1994. We offer quality software products and related services to a rapidly growing worldwide clientele. Our services include

  • System (descriptive and optimization) model development and customization

  • Optimization algorithm development and customization

  • Presentation of lectures, workshops and intensive courses.

    Our primary expertise is related to nonlinear systems analysis and optimization. This includes the development of deterministic and stochastic algorithms and software for global and local optimization, for a broad range of applications in the sciences, engineering, economics and finances.

    We have been developing professional optimization software products since the late 1980s. The integrated Lipschitz Global Optimizer (LGO) suite of global and local solvers handles complex system models defined by computable, continuous, or Lipschitz functions, currently in up to thousands of variables and constraints. Model size limitations essentially depend on the available hardware/software platform, and the practically affordable program execution time. Customized algorithm and software development options are available, as a consulting service.

    The optimization models themselves can be even "black box" systems, with (merely) computable information, without the need for explicit function forms, derivatives, or higher order information. This unique feature makes our software products applicable in a large variety of contexts, including very complex models, closed modules, or confidential applications developed by our clients.

    Software Products

    Our products are developed and maintained in cooperation with world-class partners. The currently available software implementations - offered for compiler platforms, optimization modeling languages, and integrated scientific-technical computing systems - are listed below.

    All software products are available either directly from Pintér Consulting Services and/or - in certain cases, exclusively - from our developer partners. Professional, non-profit research, and educational licenses are offered (with significant discounts in the latter two cases).

    Further implementations are in progress; related suggestions are welcome.
