Perhaps you should try some spelling variations:
"modified adam optimisation algorithm" » "modified adam optimization algorithms", "modified adam estimation algorithm", "modified _ optimisation algorithm", "modified game optimization algorithm", "modified df optimisation algorithm", "modified near optimisation algorithm"
"modified invasive estimation algorithms" » "modified invasive estimation algorithm", "modified invasive optimization algorithms", "modified invasive approximation algorithms", "modified invasive ventilation algorithms", "modified passive estimation 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 invasive estimation algorithms") OR ("modified adam optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( modified invasive estimation algorithms ) or ( modified adam optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive estimation algorithms") or ("modified adam optimisation algorithm"))*.
