Perhaps you should try some spelling variations:
"modified optimal optimisation algorithm" » "modified optimal optimization algorithms", "modified optimal estimation algorithm", "modified optimal estimation algorithms", "modified thermal optimisation algorithm"
"modified objective evolutionary algorithm" » "modified objective evolution algorithm", "modified objective solution algorithm"

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 optimal optimisation algorithm") OR ("modified objective evolutionary algorithm"))~.
• Removing quotes may allow a broader search: (( modified optimal optimisation algorithm ) or ( modified objective evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified optimal optimisation algorithm") or ("modified objective evolutionary algorithm"))*.
