```
public class RewriteMatrixMultChainOptimizationSparse
extends RewriteMatrixMultChainOptimization
```
Rule: Determine the optimal order of execution for a chain of matrix multiplications Solution: Classic Dynamic Programming Approach: Currently, the approach based only on matrix dimensions and sparsity estimates using the MNC sketch Goal: To reduce the number of computations in the run-time (map-reduce) layer
