[ ] ostaszewski paper (focus on rotosolve and think about rotoselect as related and future work considering CRP gate selection)
[ ] generalized parameter shift rule (should explain how pennylane implements rotosolve and the meaning of frequencies in this context in particular. This might also be related to pennylane fourier)
[ ] ...other papers. One of these papers should mention (afaik) that 6 evaluations are enough to optimize CRP
especially the sequential optimal paper
