Summary: Incorporate sparsity in lower bound costs Key: SYSTEMML-2160 URL: https://issues.apache.org/jira/browse/SYSTEMML-2160 Project: SystemML Issue Type: Sub-task Reporter: Matthias Boehm So far, the codegen optimizer computes the lower bound costs for cost-based pruning without proper awareness of sparsity exploiting operators. This led to suboptimal plans because sub areas of the search space are pruned too eagerly. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
