Perhaps you should try some spelling variations:
"modified changing optimization algorithmsss" » "modified changing optimisation algorithm", "modified changing estimation algorithms", "modified changing optimisation algorithmss", "modified changing estimation algorithmsss", "modified changing estimation algorithmss", "modified staffing optimization algorithmsss", "modified caging optimization algorithmsss"
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithms", "modified objective estimation algorithm", "modified multiobjective optimization 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 objective optimization algorithms") OR ("modified changing optimization algorithmsss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithms\") OR (\"modified changing optimization algorithmsss\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithms ) OR ( modified changing optimization algorithmsss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithms") OR ("modified changing optimization algorithmsss"))*.
