Perhaps you should try some spelling variations:
"modified parameter optimized algorithm" » "modified parameter optimization algorithm", "modified parameter optimized algorithms", "modified parameter optimizer 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 parameter optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( modified changing solution algorithm ) OR ( modified parameter optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified changing solution algorithm") OR ("modified parameter optimized algorithm"))*.
