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

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 objective optimization algorithm\") OR (\"modified adam solutions algorithm\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified adam solutions algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified adam solutions algorithm"))*.
