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

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

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