Top-down start
- We will start with a top-down view, with a simple harmonic oscillator problem in one dimension as case.
- Thereafter we continue with implementing the simplest possible steepest descent approach to our two-electron problem with an electrostatic (Coulomb) interaction. Our code includes also importance sampling. The simple Python code here illustrates the basic elements which need to be included in our own code.
- Then we move on to the mathematical description of various gradient methods.
