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 learning methods algorithm" » "mobile learning methods algorithm", "modified caging methods algorithm", "modified nursing methods algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"designed network optimisation algorithm\") OR (\"modified learning methods algorithm\"))~".
• Removing quotes may allow a broader search: (( designed network optimisation algorithm ) OR ( modified learning methods algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimisation algorithm") OR ("modified learning methods algorithm"))*.
