Perhaps you should try some spelling variations:
"modified objective optimisation algorithms" » "modified objective optimisation algorithm", "modified objective optimization algorithms", "modified objective estimation algorithms", "modified multiobjective optimization algorithms"
"modified allocation optimization algorithm" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified location optimization 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 optimization algorithm") or ("modified objective optimisation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified allocation optimization algorithm") OR ("modified objective optimisation algorithms"))*.
• Removing quotes may allow a broader search: (( modified allocation optimization algorithm ) or ( modified objective optimisation algorithms ))*.
