From: Alignment between initial state and mixer improves QAOA performance for constrained optimization
The figures from left to right display the depth-1 QAOA energy landscape with gamma search space [0, 2000π], [0, 100π], and [0, 2π]. By applying a rescaling factor and fixing the search space as [0, 2π], they are equivalent to setting the rescaling factors as 1000, 50, and 1, respectively. In this example, a rescaling factor of 50 encompasses high-quality local minima in the landscape.
