## DeltaBlue for Delphi v.1.0

By W&C Information Consultants.

Freeware + source 24 Feb 2003### Description

First official Open Source Project is a Delphi (Object Pascal) implementation of the Delta Blue incremental dataflow constraint solver.What is a incremental dataflow constraint solver? Simply put, it maintains relationships between variables and when a variable changes, automatically computes which variables are dependant and what their new values should be.

For example: Given the constraint A + B = C, when either A or B changes, C will be recalculated; But if C changes, Delta Blue will also recalculate A or B depending on the strength of the constraint.

## KCompiler v.1.20

By DOMIN Software.

17 Mar 2003### Description

KCompiler is a Delphi component purposed to compile and evaluate mathematical expressions (formulas), for example, "2*x+cos(y)".KCompiler checks the syntax of given expression and generates real machine code to evaluate it. The code is highly optimized for x86-compatible processors produced since 1995, so formula evaluation process with KCompiler becomes faster than evaluation of the same formula with the most of other compilers, for example, Borland Delphi.

You can easily extend possibilities of KCompiler with functions in your Delphi program and they will be called in the fastest way or use free library KLib (included). Also you may add external variables of different types (the most of Delphi scalar types are included).

Use KCompiler to calculate formulas that are unknown at the stage of program compilation or to achieve greater speed with your Delphi application.

Major features:

- common arithmetic operations +, -, *, / and parenthesis (, )
- expression simplifying
- deep analyzing of formula
- great speed of calculations
- large set of optimizations
- syntax errors handling
- data alignment
- extendable variable list
- large set of supported variables' types
- extendable function list
- quick function parameters passing
- smart function call mode
- support for multithreaded computing.
