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