Time-Optimal APSP and Matrix Multiplication in Classes of Linear Neighborhood Complexity
This work presents $O(n^2)$-time optimal algorithms for $n$-vertex graphs coming from a class of linear neighborhood complexity for the following problems: All-Pairs Shortest Paths, and the multiplication of the adjacency matrix of the input graph with any $n \times n$ matrix.
