Perhaps you should try some spelling variations:
"modified choosing optimisation algorithm" » "modified choosing optimization algorithms", "modified choosing estimation algorithm", "modified choosing estimation algorithms", "modified caging optimisation algorithm"
"modified parameters optimized algorithms" » "modified parameters optimized algorithm", "modified parameters optimizer algorithms", "modified parameters optimization algorithms"

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 choosing optimisation algorithm\") OR (\"modified parameters optimized algorithms\"))~".
• Removing quotes may allow a broader search: (( modified choosing optimisation algorithm ) OR ( modified parameters optimized algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified choosing optimisation algorithm") OR ("modified parameters optimized algorithms"))*.
