Pintér Consulting Services, Inc.

Company Background, Products and Services

Introduction

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

  • Systems model development

  • Optimization algorithm development and customization

  • Lectures, workshops, and intensive courses, in addition to full (semester-long) courses.

    Professional Expertise

    Our primary expertise is related to nonlinear systems analysis and optimization. This specifically includes the development of algorithms and software for global and local optimization. PCS and its partners have been developing optimization software products that can be applied to solve a broad range of decision problems arising in engineering, economics, and the sciences.

    Our flagship product, the Lipschitz Global Optimizer (LGO) suite of global and local solvers can handle system models defined by (Lipschitz-)continuous functions. The optimization model can be a complete "black box", without the need for explicit function forms, derivatives, or higher order analytical information. This key feature makes LGO (and our related software products) applicable in a large variety of contexts, including the optimization of complex models, entirely closed modules, or confidential applications developed by our clients.

    The solvable model size limitations essentially depend only on the available hardware/software platform, and on the practically affordable model + solver program execution time. Currently, we offer solvers to handle models with up to several thousand variables and general constraints.

    Customized algorithm and software development options are available, as a consulting service.

    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 environments, 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.
