Drools is a set of projects focusing on intelligent automation and decision management, most notably providing a forward-chaining and backward-chaining inference-based rule engine, …

As a business rules developer, you can use Drools to design a variety of decision services. This document describes how to create and test an example traffic violation project based on the …

For example, the screenshot below shows a configuration where three runtimes have been defined: a Drools 4.0.7 runtime, a Drools 5.0.0 runtime and a Drools 5.0.0.SNAPSHOT runtime.

The Drools rule engine in Drools is a hybrid reasoning system that uses both forward chaining and backward chaining to evaluate rules. A forward-chaining rule system is a data-driven system …

Many modules of Drools (e.g. drools-core, drools-compiler) have a file named kie.conf containing the names of the classes implementing the services provided by the corresponding module.

Build, Deploy, Utilize and Run In this section you will learn the paradigms to use Drools library as part of KIE (Knowledge Is Everything) for Building, Deploying and Running your Drools-based …

When creating a new Drools project, the plugin will automatically use the default Drools runtime for that project, unless you specify a project-specific one. You can do this in the final step of …

Drools implements and extends the Rete algorithm; Leaps used to be provided but was retired as it became unmaintained. The Drools Rete implementation is called ReteOO, signifying that …

The document takes things to the next level pushing Drools forward as a hybrid engine, not just a capable production rule system, but also melding in logic programming (prolog) with functional …

This document will explain the rules that drive the simulation and discuss the Drools parts of the implementation. We'll first introduce the grid view, shown below, designed for the visualisation …
