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