In the last lecture, we saw the graph powering method, which allows us to increase the soundness gap but has the drawback of increasing the alphabet size from |Σ| to |Σ|dt (where |Σ| is a constant). In this lecture, we describe how to reduce the alphabet size (from |Σ|dt back to |Σ|), while causing only a small decrease in the gap (and a constant factor increase in the constraint graph size). T...
