As a result, land was concentrated in the hands of relatively few wealthy, plantation-owning families, and production was largely dependent on slave labor. The intermixing of these Europeans and Blacks, as well as the native
Quantum refereed game space of this SPD is exponential (from the tensor product states) in formula_1, and the SDP has a size polynomial in the dimension of its input and output space. Since there are efficient algorithms that can solve SDP in polynomial-time, it follows that QRG ⊆ EXP. Quantum refereed game Quantum refereed game in quantum information processing is a class of games in the general theory of quantum games. It is played between two players, Alice and Bob, and arbitrated by a referee. The referee outputs the pay-off for the players after interacting with them for a fixed number of rounds,
