‌Xpress Mosel contains drivers for access to text, XML, R, Python, MATLAB, CSV, Excel, Hadoop's HDFS, OBDC and Oracle databases. ‌ Integration with Tableau ® for FICO facilitates drag and drop creation of visualizations. ‌ Uses Xpress Mosel, the most flexible modeling and configuration language available, to provide an easy-to-learn, robust way to interact with Xpress solver engines FICO® Xpress Insight. The optimization model at the heart of the application is authored using the FICO® Xpress-Mosel modeling language and solved using Xpress Solver. As such, it is assumed that the developer has experience with developing optimization models using Mosel, the Xpress Workbench editor, and the Solver algorithms. The solver.

Einführung in Xpress-Mosel Matthias Silbernagl Computerblockpraktikum zur linearen Optimierung Gliederung Inhaltsverzeichnis 1 Mosel-Grundlagen Mosel this functionality is explained in a separate Xpress Whitepaper entitled Generalized file handling in Mosel. 1.6 Contents of this paper The first part of this paper gives an overview on the general architecture of the system and introduces its language by means of a small example. Certain aspects of the Mosel language ar As an example, the 'mmxprs' module extends the Mosel language with the procedure 'maximize' that optimizes the current problem using the Xpress-Optimizer. This modularized structure offers various advantages: • Once compiled, a model can be run several times, for instance with different data sets, without the need for recompiling it

• The mmquad module extends the Mosel language with a new type for representing quadratic expressions.To use this module, the following line must be included in the header of the Mosel model file: . uses 'mmquad' The first section presents the new functionality for the Mosel language that is provided by mmquad, namely the new type qexp and a set of subroutines that may be applied to objects of.
• Upon startup, Mosel uses as the default for this list the value of the environment variable MOSEL_DSO completed by the subdirectory dso in the Mosel installation directory. This directory is taken from one of the environment variables MOSEL , XPRESSDIR or XPRESS (note that Mosel console still works even if none of these variables is defined)
• Xpress-Mosel. Multi-solver, multi-problem, multi-model, multi-node modeling and problem solving.

• After a short discussion of the history of modeling languages and the contributions made by FICO Xpress Mosel to this evolution, we point to a number of implementation variants for the classical travelling salesman problem (TSP) using different MIP-based solution algorithms as an example of employing Mosel in the context of parallel or distributed computing, for interacting with a MIP solver.

Procedures and functions Mosel instance management. The type Mosel is used to reference a Mosel instance. Before an instance can execute commands (like loading or running a model), it must be connected.Connecting an instance consists in starting an additional operating system process running Mosel: this is done by the connect function The parameter values need to be taken in the same order as they appear in the subroutine in the Mosel program. For example, if we want to implement a procedure do_something with the following prototype procedure do_something(val1:real, num:integer, arr:array(range) of mpvar, val2:real) we need to take the parameters in the following order from the stack (ctx is the Mosel context): XPRMarray.

Xpress-Mosel, a commercial product since 2001 (originally developed by Dash Optimization, now FICO), provides a complete environment for developing, testing and deploying optimization applications. Development and analysis of optimization models written with the Mosel language is aided by the graphical environment Xpress-IVE, and tools such as the Mosel debugger and profiler. The Mosel. Examples: Xpress-Mosel Language Reference Manual 3 Running Mosel Introduction The Mosel environment may be accessed either through its libraries or by means of two applications, perhaps the simplest of which is the Xpress-MP integrated visual environment, Xpress-IVE. Using a popular graphical interface, models can be developed and solved, providing simple access to all aspects of Mosel's.

Fully Compatible. Risk Solver Platform and Premium Solver Platform are 100% upwardly compatible from the standard Excel Solver. Your existing models can be solved with no changes, faster and more easily than before. And your VBA code designed to control the standard Solver will work as-is with Risk Solver Platform or Premium Solver Platform and the XPRESS Solver Engine -- just select the. Data Scientists and Operations Researchers can quickly deploy their analytic and optimization model whether it is written in Python or Xpress Mosel into Xpress Insight applications. UI development of interactive analytic applications is easily done via drag & drop in View Designer or our mark-up language VDL (View Definition Language). Xpress Insight provides out-of-the-box scenario management. FICO ® Xpress Optimization besteht aus vier Kernkomponenten: FICO ® Xpress Insight, FICO ® Xpress Executor, FICO ® Xpress Solver und FICO ® Xpress Workbench. FICO Xpress Solver hilft Kunden dank seiner umfassenden Palette an branchenführenden Optimierungsalgorithmen und -technologien bei der Lösung ihrer kompliziertesten und komplexesten Geschäftsprobleme With the 'mmsheet.csv:' I/O driver, when you select columns via the header titles it does not really matter in which columns they are located, or even in which order they occur in the CSV data file Mosel comes with a default set of modules (mmetc, mmsystem, mmodbc, mmquad, and mmx-prs) but a user can implement his own modules which are a special kind of Dynamic Shared Object (DSO) written in the C (or C++) programming language. The Mosel Native Interface is a set of conventions that a DSO must respect to be accepted as a module by Mosel.
