An interesting analogy from the author. VQE is like tuning a guitar.

• the quantum part would be like assembling the strings of the guitar
• in the classic part, is like to tune each of the strings: play, check the result against expected, tighten or loosen the string, test again

It’s not a perfect analogy, but it helps give you an idea of ​​the concept.
