Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization algorithms"
"modified adam convolution algorithms" » "modified adam evolution algorithm", "modified adam solution algorithm", "modified df convolution algorithms", "modified near convolution algorithms"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adam convolution algorithms\") OR (\"modified objective optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adam convolution algorithms ) OR ( modified objective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adam convolution algorithms") OR ("modified objective optimization algorithms"))*.
