TbcParser implements parse once-evaluate many times type of parsing for mathematical expressions given as strings. TbcParser is especially useful in scientific, engineering programs. It allows creation of custom variables and functions to be used in the expressions. It#s internal arithmetic uses #Extended# storage for floating point numbers. This mathematical expression parser component parses and evaluates a mathematical expression that may contain variables and functions. Examples to typical expressions are: SIN(3.14)+5^2+POW(2,7)-MAX(10,20) ( [ SIN(X)^2 ] + COS(1) ) * PI/2 '( COSH(2.71)+ SINH( COS(0.5) * POW(0.2345, 0.67) )) - LOG(1-X^2+X^5)' (90+292*POW(X,0.31))*(1+0.025*LOG(Y))*(1-1*POW(Y+X,1.09)) '25993.894*EXP(-1.53389*(X-32))*POW(X, 0.13547)*POW(Y, 0.38603)*EXP(-0.36222*Y)' The user can add/remove his/her own custom variables and functions to be used in the expression. To be efficient in repeated calculations, parser creates a parse tree at first and reuses this parse tree for each evaluation without the need to reparse. If Optimization is on, the parse tree will be optimized by calculating constant expression sections at once so that further evaluation requests will be quicker. TbcParser can be used with Delphi 4, 5 and C++ Builder 3, 4, 5 TbcParser full version comes with the Pascal source code and there is also a help file for reference and a demo application for aid in getting started.

The CronJob component is the thread-based alarm implementation for Delphi/BCB which acts like cronjob utility in Unix. The component produces periodical OnAlert events by schedule specified in CRON format (actually it uses extended CRON format with new "seconds" field, to let the event to be triggered even every second). To specify the moments when the component should trigger the OnAlert event, the component uses the CRON format (all who worked in Unix must be aware about this utility, this is daemon of scheduled, periodically executed tasks). The authors of CronJob component has very liked an idea of describing the periodical events of any complexity, tiered to astronomical time, in simple text string. We have used slightly modified CRON format, added seconds field and altered the rules of describing the lists of numbers. The package includes 2 bonus components: * AccurateTimer -- thread-based timer which periodically triggers the OnTimer events by specified Interval, but unlike standard TTimer, which based on Win32API and thus loses timer messages on high application overload, this timer runs in the separate thread and accurately triggers each OnTimer event at right time. It also allows to specify the Interval with higher precision (less than 55msec, limited in Win9x) and does not dependent to the system-wide limitations.) * AwayTimer -- monitors user activity and increase its time counter when keyboard and mouse are inactive (user distracted from PC or goes away). Also it triggers special event when system is about to start the screensaver, or after some defined period of user inactivity.

Data miner is a set of components for classification for Borland Delphi written in 100% VCL. The algorithms included cover: KNN and Naive Bayes plus a third completely new algorithm named Linear Classifier. The algorithms can work on real and discrete data and can be connected to a TDataSet descendant. They appropriatelly handle missing data and are all capable of incremental learning. The package includes a demo with reference results on standard domains, examples of usage and performance tests. The package also contains a 9 page document giving the user a rush introduction to all key charachteristics of classification algorithms. The classification algorithms from the Data Miner are used to tackle the same kind of problems as neural networks.

Expandable formula parser. Can handle variables. When the parser needs the value of a variable, it creates an event to get it. Very fast if using the same formula with different values for variables, because it works in two steps: parsing to a tree structure and calculate. Different priorities for operators. Unary (exampe: sin) and binary (example: +) operators. List of operators is easy expandable to custom problem. Demo application. Source code on purchase.

The TKAParser component is an expression parser, calculator and spread sheet engine. It can (1) Evaluate mathematical and string expressions that contain numbers, predefined variables and formulas. A mathematical expression may have any commonly used math functions. A string expression may have any commonly used string function. (2) Transparently track formula / variable dependencies. Consequently, the parser needs to re-evaluates a formula only when the value of a dependent variable changes, a feature that enables it to perform hundreds of complex expression evaluations every second. A caching mechanism further optimizes expression evaluation making the parser#well# Kick Ass! · Work with any number of user defined functions.

The RapidEvaluator Delphi component is a real COMPILER of the mathematical expressions (formulas), such as "SIN(0.5)+COS(x)*2". It checks the expression syntax and generates the real machine code for evaluating given formula. The code generated is optimized to use FPU in order to achieve the maximal speed of calculations: it's even up to 2 TIMES FASTER THAN DELPHI'S 32-bit code. To satisfy your personal needs you can add external user-defined variables and functions in addition to built-in ones. Use RapidEvaluator to calculate formulas that is unknown at the stage of program compilation, for example to plot and tabulate functions, to make numerical computations and so on.
