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