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 level evolution algorithm" » "modified level solution algorithm", "modified level evolutionary algorithm", "modified level convolution algorithms", "modified legal revolution algorithm", "modified global evolution algorithm", "modified level production 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 level evolution algorithm\") OR (\"modified notion optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified level evolution algorithm ) OR ( modified notion optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified level evolution algorithm") OR ("modified notion optimisation algorithm"))*.
