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