Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified notion estimation algorithms", "modified network optimization algorithm"
"modified charging optimized algorithm" » "modified charging optimized algorithms", "modified charging optimizer algorithms", "modified choosing optimizer algorithm", "modified caging optimized algorithm", "modified carbon optimized 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: "((\"modified charging optimized algorithm\") OR (\"modified notion optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified charging optimized algorithm ) OR ( modified notion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging optimized algorithm") OR ("modified notion optimisation algorithm"))*.
