Kamke Test Suite - SymPy

This repository contains all the 1940 ODEs from Differentialgleichungen Lösungsmethoden und Lösungen by Kamke. To view the results on the latest SymPy version, visit the home page. The results of the test suite are available in JSON format in the json folder.

Run the Test Suite

If you want to run the test suite, clone the repository. To run the entire test suite, run -

python test_kamke.py

This will generate a folder with the results of the run in JSON format. To generate HTML pages from these files, run -

python test_kamke.py --html

Command Line Arguments

There are different ways to run the test suite using command line arguments. To view all the arguments, use -h or --help.

python test_kamke.py --help

usage: test_kamke.py [-h] [-e EXAMPLE] [-ch CHAPTER] [--hint HINT] [--all_hints] [--verify] [--dsolve_time DSOLVE_TIME] [--checkodesol_time CHECKODESOL_TIME]
                     [--html] [-rp]

optional arguments:
  -h, --help            show this help message and exit
  -e EXAMPLE, --example EXAMPLE
                        Name of the example in the format {chapter_no}.{problem_no} Specify all to test all examples
  -ch CHAPTER, --chapter CHAPTER
                        Chapter no. Tests all examples of a chapter
  --hint HINT           Hint to be used to solve the ODEs
  --all_hints           Solve the ODE with all matching hints
  --verify              Verify the solution from dsolve using checkodesol
  --dsolve_time DSOLVE_TIME
                        Timeout duration (in seconds) for dsolve
  --checkodesol_time CHECKODESOL_TIME
                        Timeout duration (in seconds) for checkodesol
  --html                Generate HTML reports from JSON files
  -rp, --remove_prev    Remove files generated from previous runs

Examples

Run the 5th example from the 2nd chapter

python test_kamke.py --example 2.5

Run all examples from chapter 3

python test_kamke.py --chapter 3

Solve all examples from chapter 5 using the hint factorable

python test_kamke.py -ch 5 --hint factorable

Find solutions for all matching hints from dsolve for the example 1.1

python test_kamke.py -e 1.1 --all_hints

Find the solution to example 2.10 and verify if it is correct

python test_kamke.py -e 2.10 --verify

Find the solutions to all examples in chapter 7 with a timeout of 30 seconds for dsolve and 20 seconds for checkodesol for each ODE.

python test_kamke.py -ch 7 --dsolve_time=30 --checkodeosol_time=20

Run the entire test suite and delete any files from previous runs.

python test_kamke.py --remove_prev
