Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"modified changing evolutionary algorithm" » "modified changing evolution algorithm", "modified changing solution algorithm", "modified caging evolutionary 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 allocation optimisation algorithm") OR ("modified changing evolutionary algorithm"))~.
• Removing quotes may allow a broader search: (( modified allocation optimisation algorithm ) or ( modified changing evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimisation algorithm") or ("modified changing evolutionary algorithm"))*.
