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