Perhaps you should try some spelling variations:
"modified aging optimization algorithmss" » "modified aging optimization algorithms", "modified aging estimation algorithms", "modified aging estimation algorithm", "modified staffing optimization algorithmss", "modified game optimization algorithmss", "modified caging optimization algorithmss"
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"

Try widening your search to All Fields.

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