NxBRE

Categories: Math - Logic - AI - Rules

Author: David Dossot

Latest version: 2.5.1
Added 2004-02-06Updated 2006-06-08

Open-source rule engine, and lightweight Business Rule Engine (aka Rule-Based Engine).
NxBRE offers to approaches:
- the Flow Engine, which uses XML as a way to control process flow for an application in an external entity. It is basically a wrapper on C#, as it offers all its flow control commands (if/then/else, while, foreach), plus a context of business objects and results. It is a port of Sloan Seaman's JxBRE v1.7.1 (Java platform) to C#.
- the Inference Engine, which is a forward-chaining (data driven) deduction engine and that supports concepts like Facts, Queries and Implications (as defined in RuleML 0.8 Datalog) and like Rule Priority, Mutual Exclusion and Precondition (as found in many commercial engines). It is designed in a way that encourages the separation of roles between the expert who designs the business rules and the programmer who binds them to the business objects.

WebCab Optimization for .NET

Home Page

Categories: Math - Logic - AI - Rules

Author: WebCab Components

Latest version: 2.6
Added 2006-12-05

Procedures for solving and performing sensitivity analysis on uni and multi dimensional, local or global optimization problems which may or may not have linear constraints. Specialized Linear programming algorithms based on the Simplex Algorithm and duality are included along with a framework for sensitivity analysis w.r.t. boundaries (duality, or direct approach), or object function coefficients.

Features include:
- local unidimensional optimization: fast "low level" algorithms (where the weight is on speed and not the accuracy of the results); bracketing algorithm (find an interval where at least one extrema of a continuous function exists); locate algorithms (converge to the extrema if the extrema is bracketed and the function under consideration is continuous); accurate "high level" algorithms;
- global unidimensional optimization: finds global minima/maxima;
- unconstrained local multidimensional optimization;
- unconstrained global multidimensional optimization;
- constrained optimization for derivable functions with linear constraints;
- linear programming: here the functions are linear and the constraints are linear;
- sensitivity analysis: stability of the value and location of the extremum.
