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 caging optimizer algorithm" » "modified caging optimizer algorithms", "modified caging optimized algorithm", "modified caging optimized algorithms", "modified choosing optimizer algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified allocation optimisation algorithm") or ("modified caging optimizer algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified allocation optimisation algorithm") OR ("modified caging optimizer algorithm"))*.
• Removing quotes may allow a broader search: (( modified allocation optimisation algorithm ) or ( modified caging optimizer algorithm ))*.
