CostEstimator (Apache SystemDS 3.3.0-SNAPSHOT API)

java.lang.Object
- org.apache.sysds.resource.cost.CostEstimator

```
public class CostEstimator
extends Object
```
Class for estimating the execution time of a program. For estimating the time for new set of resources, a new instance of CostEstimator should be created. TODO: consider reusing of some parts of the computation for small changes in the resources
