The prototype is developed using Python 3.9 in PyCharm. You can import the project into PyCharm or another IDE of your choice that supports Python development.

To run the prototype, the following packages must be installed:

• gmpy2==2.1.5
• mpmath==1.3.0
• numpy==1.24.3
• sympy==1.11.1

You can install these packages using pip with the following command:

pip install gmpy2==2.1.5 mpmath==1.3.0 numpy==1.24.3 sympy==1.11.1
