Function points were defined in 1979 in Measuring Application Development Productivity by Allan J. Albrecht at IBM. [4] The functional user requirements of the software are identified and each one is categorized into one of five types: outputs, inquiries, inputs, internal files, and external interfaces.
The Simple Function Point (SFP) method [1] is a lightweight Functional Measurement Method. The Simple Function Point method was designed by Roberto Meli in 2010 to be compliant with the ISO14143-1 standard and compatible with the International Function Points User Group (IFPUG) Function Point Analysis (FPA) method.
This is a method for analysis and measurement of information processing applications based on end user functional view of the system. The MK II Method (ISO/IEC 20968 Software engineering—Mk II Function Point Analysis—Counting Practices Manual [ 1 ] ) is one of five currently recognized ISO standards for Functionally sizing software.
The function point count provides measurement of software size, which is the sum of the data movements for a given functional requirement. It may be used to estimate (and benchmark) software project effort, cost, duration, quality and maintenance work.

IFPUG owns Function Point Analysis (FPA) as defined in ISO 20296 [4] which specifies the definitions, rules and steps for applying the IFPUG's functional size measurement (FSM) method. FPA can be traced to the work of Allan Albrecht of IBM [ 5 ] who pioneered functional sizing in 1979 which derived a functional size of product value distinct ...
In applied mathematics, topological data analysis (TDA) is an approach to the analysis of datasets using techniques from topology. Extraction of information from datasets that are high-dimensional, incomplete and noisy is generally challenging.
In numerical analysis, fixed-point iteration is a method of computing fixed points of a function.. More specifically, given a function defined on the real numbers with real values and given a point in the domain of , the fixed-point iteration is + = (), =,,, … which gives rise to the sequence,,, … of iterated function applications , (), (()), … which is hoped to converge to a point .
