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 trace evolution algorithm" » "modified trace solution algorithm", "modified trace evolutionary algorithm", "modified trace convolution algorithms", "modified time evolution algorithm", "modified traces evolution algorithm", "modified male evolution algorithm", "modified orca evolution 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 trace evolution algorithm\") OR (\"modified notion optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified trace evolution algorithm ) OR ( modified notion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified trace evolution algorithm") OR ("modified notion optimisation algorithm"))*.
