Perhaps you should try some spelling variations:
"modified df optimisation algorithm" » "modified df optimization algorithms", "modified df estimation algorithm", "modified df estimation algorithms", "modified _ optimisation algorithm", "modified _ optimization algorithm", "modified qoe optimization algorithm", "modified adam optimisation algorithm", "modified bi1 optimisation algorithm"
"modified adaptive evolution algorithm" » "modified adaptive solution algorithm", "modified adaptive evolutionary algorithm", "modified adaptive convolution algorithms", "modified adaptive ventilation algorithm", "modified passive evolution algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified df optimisation algorithm") or ("modified adaptive evolution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified df optimisation algorithm") OR ("modified adaptive evolution algorithm"))*.
• Removing quotes may allow a broader search: (( modified df optimisation algorithm ) or ( modified adaptive evolution algorithm ))*.
