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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified make optimization algorithmss\") OR (\"modified objective optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified make optimization algorithmss ) OR ( modified objective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified make optimization algorithmss") OR ("modified objective optimisation algorithm"))*.
