Perhaps you should try some spelling variations:
"modified adam optimization algorithms" » "modified adam optimisation algorithm", "modified adam estimation algorithm", "modified adam optimized algorithms", "modified game optimization algorithms", "modified stage optimization algorithms", "modified _ optimization algorithms", "modified df optimization algorithms", "modified near optimization algorithms"
"modified invasive estimation algorithms" » "modified invasive estimation algorithm", "modified invasive optimisation algorithm", "modified invasive approximation algorithms", "modified invasive ventilation algorithms", "modified passive estimation algorithms"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified invasive estimation algorithms") or ("modified adam optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive estimation algorithms") OR ("modified adam optimization algorithms")).
• Removing quotes may allow a broader search: (( modified invasive estimation algorithms ) or ( modified adam optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive estimation algorithms") or ("modified adam optimization algorithms"))*.
