Perhaps you should try some spelling variations:
"modified adaptive optimisation algorithm" » "modified adaptive optimization algorithms", "modified adaptive estimation algorithm", "modified adaptive estimation algorithms", "modified passive optimisation algorithm"
"modified write optimized algorithms" » "modified write optimized algorithm", "modified write optimizer algorithms", "modified write optimization algorithms"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified write optimized algorithms") OR ("modified adaptive optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified write optimized algorithms ) or ( modified adaptive optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified write optimized algorithms") or ("modified adaptive optimisation algorithm"))*.
