Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective estimation algorithms", "modified objective estimation algorithm", "modified objective optimized algorithms", "modified multiobjective optimization algorithms"
"modified made optimisation algorithm" » "modified made estimation algorithm", "modified made estimation algorithms", "modified game optimization algorithm", "modified market optimization algorithm", "modified stage optimization algorithm", "modified male optimisation algorithm", "modified adam optimisation algorithm", "modified df optimisation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified made optimisation algorithm") or ("modified objective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified made optimisation algorithm") OR ("modified objective optimization algorithms")).
• Removing quotes may allow a broader search: (( modified made optimisation algorithm ) or ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified made optimisation algorithm") or ("modified objective optimization algorithms"))*.
