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.

EquTranslator v.2.0

By Easy Math Solution.

Freeware 04 Sep 2006

Description

It's a fast equation parser/evaluator with parse-tree builder and user-friendly interface for parsing and calculation a run-time defined math expression.

The math expressions is represented as string in a function style F(x1, x2,..., xn) =f(x1, x2,..., xn), where F(x1, x2,..., xn) - declares number and names of the variables;

f(x1, x2,..., xn) - math expression may contain:

  • variables x1, x2,..., xn and numbers,
  • arithmetic operations + - * / ^,
  • supporting a large set of math functions: sqrt, sin, exp, cos, tan, ln, abs, acos, asin, atan, cosh, log10, sinh, tanh,
  • constants e= 2.71828182845904 and pi= 3.14159265358979, and
  • user defined functions and constants.
For example:
  • F(x, y) = 3*x^2+y^2+e/4,
  • F(x1, x2, y) = (x1-sin(x2))/y,
  • F()=5+6+pi.
Algorithm, which is used here, has been developed and implemented by Easy Math Solution and has different binary (static link library, dynamic link library and COM) implementation and programming approach (procedural and object oriented). It allows using EquTranslator in C/C++, C#, Delphi, VB and other languages and systems that can understand dll and COM.

KCompiler v.1.20

By DOMIN Software.

Shareware 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.
