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