I am aware that it's possible to use QAOA to solve QUBO problems. However, I've recently seen some sources mentioning the possibility of solving HOBO/HUBO problems using QAOA as well [1][3].
While I understand that quadratization from HOBO/HUBO to QUBO could be done [1][2], I'm trying to understand if it's actually possible to solve problems with higher-order polynomials using QAOA without quadratizing them. Unfortunately, I haven't been able to find too many sources discussing this subject.
