I read that there is a $\Omega(n^3)$ lower bound for $(max,+)$ matrix multiplication (with $n\times n$ matrices). This is the matrix product defined as: $(A\cdot B)_{ij}:=\max^n_{k=1}\{A_{ik}+B_{kj … }\}$, for some $n\times n$ matrices $A$ and $B$. This lower bound means that the trivial algorithm is the best one. Is there a better algorithm if we restrict the values to be in a finite set? For …
