v38 v39 4 4 == 1. Introduction == 5 5 === 1.1 Target Audience === 6 This manual is intended for end users, domain experts and students who are not necessarily familiar with algorithm development in .NET. It therefore focuses on the graphical user interface and how to configure, customize and extend the available standard algorithm already available in HeuristicLab 3.3 for a particular problem without writing (a lot of) code. We believe that a successive transfer of competence in algorithm development from heuristic optimization experts to users working on real-world applications would be very beneficial for the community as a whole. This manual will slowly guide you through a number of [#Tutorials tutorials] after which we hope even novice users will no longer have to use metaheuristics as black box techniques, but can use them as algorithms which can be modified and easily tuned to specific problem situations.6 This manual is intended for end users, domain experts and students who are not necessarily familiar with algorithm development in .NET.

Standard data types such as integers, doubles, strings, or arrays that do not offer these properties are wrapped in !HeuristicLab 3.3 objects. 16 16 * '''Variables:''' Data objects are linked to a name by storing them in a variable. 17 17 * '''Scopes:''' Scopes are containers for variables. To access a variable in a scope, the variable name is used as an identifer (has to be unique per scope). Scopes can be hierarchically organized as trees (subscope hierarchy). 18 * '''Operators:''' Each algorithm is a sequence of instructions, which are called operators in HeuristicLab 3.3. Operators are applied on scopes to access/manipulate variables and subscopes.18 * '''Operators:''' Each algorithm is a sequence of instructions, which are called operators in !HeuristicLab 3.3. Operators are applied on scopes to access/manipulate variables and subscopes. 19 19 * '''Parameters:''' Each operator defines parameters for each variable it expects and (possibly) manipulates. 20 20 * '''Engines:''' Algorithms are represented as operator graphs and executed step-by-step on virtual machines called engines. … … 23 23 24 24 == 2.

As an end user you will mostly work with the Optimizer.31 * [#PluginManager HeuristicLab Plugin Manager]: The HeuristicLab architecture is based on plugins. All optimization algorithms and problems are realized as plugins and interact with each other via well-defined and extensible interfaces. The plugin manager allows you to browse, install and update available plugins from our centralized update location or manage your own plugins.30 * [#Optimizer HeuristicLab Optimizer]: The optimizer is the core application of the !HeuristicLab Framework, providing a variety of metaheuristic algorithms, standard problem implementations, a comfortable test bench and modules for algorithm development and visualization.
