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 made optimisation algorithms" » "modified made optimisation algorithm", "modified made estimation algorithms", "modified made estimation algorithm", "modified game optimization algorithms", "modified market optimization algorithms", "modified stage optimization algorithms", "modified male optimisation algorithms", "modified adam optimisation algorithms", "modified df optimisation 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 made optimisation algorithms\") OR (\"modified objective optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified made optimisation algorithms ) OR ( modified objective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified made optimisation algorithms") OR ("modified objective optimization algorithms"))*.
