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