Perhaps you should try some spelling variations:
"modified aging estimation algorithmss" » "modified aging estimation algorithms", "modified aging estimation algorithm", "modified aging optimization algorithms", "modified lighting estimation algorithmss", "modified risk estimation algorithmss", "modified caging estimation algorithmss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified aging estimation algorithmss") OR ("modified objective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified aging estimation algorithmss\") OR (\"modified objective optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( modified aging estimation algorithmss ) OR ( modified objective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified aging estimation algorithmss") OR ("modified objective optimisation algorithm"))*.
