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