Perhaps you should try some spelling variations:
"modified adam optimization algorithms" » "modified adam estimation algorithms", "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 optimisation algorithm" » "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified passive optimisation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adam optimization algorithms") OR ("modified invasive optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam optimization algorithms\") OR (\"modified invasive optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified adam optimization algorithms ) OR ( modified invasive optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adam optimization algorithms") OR ("modified invasive optimisation algorithm"))*.
