Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"modified global solutions algorithms" » "modified global solution algorithm", "modified global evolution algorithm", "modified global convolution algorithms", "modified global evolution algorithms", "modified model solutions algorithms", "modified nodal solution 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 global solutions algorithms") OR ("modified multiobjective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified global solutions algorithms\") OR (\"modified multiobjective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified global solutions algorithms ) OR ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified global solutions algorithms") OR ("modified multiobjective optimization algorithms"))*.
