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