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