Perhaps you should try some spelling variations:
"modified passive optimisation algorithm" » "modified passive optimization algorithms", "modified passive estimation algorithm", "modified passive estimation algorithms", "modified adaptive optimisation algorithm"
"modified objective allocation algorithmssss" » "modified objective location algorithmssss"

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

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