I partially rewrote the portfolio optimisation tutorial into two new ones.

Mixers and cvar are discussed in these two tutorials, respectively.

They passed the grammar, format and sphinx check.

If the new tutorials work, I am going to delete the old one.

I refactored cvar_value, cvar_from_circuit, and cvar_from_expectation. Now jit=True saves 1/3 time.

Now jit=True saves 1/3 time

This is subtle, I expect orders of magnitude acceleration with jit. The implementation looks correct to me.
