MathSetsAnalyser

This script analyzes the math sets in two modes: INTERSECTION and AFFILIATION.
The main parameters are specified in the configuration file.
The initial math sets are entered into the script via data file.
The result of the script is the output file.

---

Mode INTERSECTION (INTS in config.ini) analyzes the math sets.

Script returns the intersection of the initial math sets.

Mode AFFILIATION (AFFL in config.ini) analyzes the math sets and predetermined point.

Script returns the predetermined point, if it belongs to the initial math sets intersection,
or the closest endpoint(s) to the predetermined point otherwise.

---

Installation

• Python (3.12)

The Python packages can be installed by running

python3 -m pip install -r requirements.txt

---

Quick Start Guide

1. Run the create_sample.py script.
   It will create the config.ini sample configuration file and the data file.txt file with sample data.
2. Then, run the run_math_sets_analyser.py script.
   A new file script_result.xml will be created that contains the calculation results.

Running MathSetsAnalyser

For math analysis of input data as a script:

• create config.ini
• create data file with initial math sets
• run python run_math_sets_analyser.py

To test MathSetsAnalyser run

pytest

---

The configuration file config.ini has the following structure:

[general]
analysis mode: INTS or AFFL
point (for AFFL mode only)

[input]
type of the data file: JSON TXT XML
path to the data file

[output]
type of the output file: JSON TXT XML
path to the output file (including name of the file)

Example of config.ini for INTERSECTION mode

[general]
mode = INTS

[input]
format = TXT
path = ../data files/input math sets

[output]
format = XML
path = ../script output files/result.xml

Example of config.ini for AFFILIATION mode

[general]
mode = AFFL
point = 1.247

[input]
format = JSON
path = ../data files/input math sets

[output]
format = TXT
path = ../script output files/result

---

The data file contains the initial math sets.

Each initial math set is given as list of ranges and points.
The math range is given as tuple and math point is given as int or float
The -inf is given as float('-inf')
The +inf is given as float('inf')
Note: For JSON data file initial math set is given as str object. So check the use of ' ' and " "

Examples of initial math sets for TXT and XML data file:
[(float("-inf"), -10.02), (10.97, float("inf"))]
[(float('-inf'), -41), -18, (51, 62.01), 77.34, (103.0, float('inf'))]
[(-89, -61), (61, 72)]
[14.021]

Examples of initial math sets for JSON data file:
"[(float('-inf'), -10.02), (10.97, float('+inf'))]"
"[float(('-inf'), -41), -18, (51, 62.01), 77.34, (103.0, float('inf'))]"
"[(-89, -61), (61, 72)]"
"[14.021]"

Example of JSON data file

[
	"[float(('-inf'), -132), -89.61, (-24, float('inf'))]",
	"[(-43, -12), (10, 27)]"
]

Example of TXT data file

[(float("-inf"), -132), -89.61, (-24, float("inf"))]
[(-43, -12), (10, 27)]

Example of XML data file

<MathSets>
    <value>[(float("-inf"), -132), -89.61, (-24, float("inf"))]</value>
    <value>[(-43, -12), (10, 27)]</value>
</MathSets>

---

Examples of the output file

JSON format (AFFILIATION mode)

"[(10, 22)]"

TXT format (AFFILIATION mode)

[-12, 10]

XML format (INTERSECTION mode)

<OutputData>
    <value>[(-77, -61), (-17, -12), (10, 22)]</value>
</OutputData>
