About IDE tutorials

Gives the prerequisites for reading this document and outlines the structure.

This manual assumes that you are familiar with the IDE graphical user interface. Read Getting Started with the IDE first if this is not the case.

You may also need to read Navigating in the documentation set for details of prerequisites, naming conventions, and other general information.

This manual is organized as follows:

• Understanding solving statistics and progress (MP models): A relatively long MIP example presents the pause feature and the display in the Progress chart of the Output window.

• Understanding solving statistics and progress (CP models): An example that uses a manufacturing problem solved by the CP Optimizer engine to describe the Statistics and Progress chart in the IDE Output window.

• Working with external data: An IP example presents the use of a spreadsheet as an external data source.

• Using IBM ILOG Script for OPL: Several examples illustrate the use of scripting through script statements in model files; the scripting language is IBM ILOG Script for OPL.

• Relaxing infeasible models: The nurse scheduling example illustrates how to use the IDE to search for relaxations and conflicts in a model that appears infeasible after execution. This feature may help you detect errors in the model or data of your project.

• Profiling the execution of a model: A tutorial shows how the IDE can help you improve your model to make it run faster while consuming less memory.

• Working with the solution pool: This section explains what solution pools are and how solution pools are populated. An example shows how you can use IBM ILOG Script to work with solution pools.

• Using the performance tuning tool: This section explains, with an example, how to use this IDE feature to fine-tune CPLEX parameters for MP models.
