Perhaps you should try some spelling variations:
"modified parameters optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithms", "modified parameters estimation algorithm", "modified parameters estimation algorithms"
"modified changing solution algorithm" » "modified changing evolution algorithm", "modified changing convolution algorithms", "modified changing evolutionary algorithm", "modified caging solution algorithm", "modified charging station 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 changing solution algorithm\") OR (\"modified parameters optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified changing solution algorithm ) OR ( modified parameters optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified changing solution algorithm") OR ("modified parameters optimisation algorithm"))*.
