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 risk optimized algorithms" » "modified risk optimized algorithm", "modified risk optimizer algorithms", "modified risk optimization algorithms", "modified write optimized algorithms", "modified bi1 optimized 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 risk optimized algorithms") or ("modified allocation optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified risk optimized algorithms") OR ("modified allocation optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified risk optimized algorithms ) or ( modified allocation optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified risk optimized algorithms") or ("modified allocation optimisation algorithm"))*.
