Perhaps you should try some spelling variations:
"modified make optimisation algorithmss" » "modified make optimisation algorithm", "modified make estimation algorithms", "modified make estimation algorithm", "modified market optimization algorithmss", "modified game optimization algorithmss", "modified stage optimization algorithmss", "modified male optimisation algorithmss"
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"

Try widening your search to All Fields.

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified make optimisation algorithmss") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified make optimisation algorithmss") OR ("modified multiobjective optimization algorithms")).
• Removing quotes may allow a broader search: (( modified make optimisation algorithmss ) or ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified make optimisation algorithmss") or ("modified multiobjective optimization algorithms"))*.
