Quadrilateral inequality optimization represents a powerful technique for optimizing certain types of dynamic programming solutions, particularly thoce involving 2D1D state transitions. The fundamental form of such DP equations is: [f_{l,r}=\min_{k=l}^{r-1}{f_{l,k}+f_{k+1,r}}+w(l,r) ] When the function w(l,r) satisfies specific properties, we c ...
