Perhaps you should try some spelling variations:
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"
"modified trace solution algorithm" » "modified trace evolution algorithm", "modified trace convolution algorithms", "modified trace evolutionary algorithm", "modified traces solution algorithm", "modified male solution algorithm", "modified orca solution algorithm", "modified exact solution algorithm", "modified nacl solution algorithm"

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