Perhaps you should try some spelling variations:
"modified global solutions algorithms" » "modified global solution algorithm", "modified global evolution algorithm", "modified global convolution algorithms", "modified global evolution algorithms", "modified model solutions algorithms", "modified nodal solution algorithms"
"modified objective allocation algorithm" » "modified objective estimation algorithm", "modified objective evolution algorithm", "modified objective predation 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 global solutions algorithms") or ("modified objective allocation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified global solutions algorithms") OR ("modified objective allocation algorithm")).
• Removing quotes may allow a broader search: (( modified global solutions algorithms ) or ( modified objective allocation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified global solutions algorithms") or ("modified objective allocation algorithm"))*.
