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

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 objective optimisation algorithm") or ("modified based optimization algorithmss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimisation algorithm") OR ("modified based optimization algorithmss")).
• Removing quotes may allow a broader search: (( modified objective optimisation algorithm ) or ( modified based optimization algorithmss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimisation algorithm") or ("modified based optimization algorithmss"))*.
