Perhaps you should try some spelling variations:
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation algorithm"
"modified global estimation algorithmss" » "modified global estimation algorithms", "modified global estimation algorithm", "modified global optimization algorithms", "modified global optimization algorithmss", "modified global edition algorithmss", "modified global variation algorithmss"

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 global estimation algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified objective optimization algorithm\") OR (\"modified global estimation algorithmss\"))".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified global estimation algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified global estimation algorithmss"))*.
