We leave it as a future work to explore a good strategy to sample from these configurations =-=[8, 9, 30]-=-. RQ3. Moreover, based on the fact that we could run SPLat on the codebase as large as Groupon PWA, we conclude the following: SPLat scales to real, large industrial code. The implementation effort fo...
