Perhaps you should try some spelling variations:
"modified adamdaptive estimation algorithm" » "modified adaptive estimation algorithm", "modified _damdaptive estimation algorithm", "modified dfdamdaptive estimation algorithm", "modified adamdamdaptive estimation algorithm"
"modified a simulation algorithm" » "modified a solution algorithm", "modified a optimisation algorithm", "modified a estimation algorithms", "modified _ simulation algorithm", "modified df simulation algorithm", "modified adam simulation algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adamdaptive estimation algorithm") OR ("modified a simulation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adamdaptive estimation algorithm\") OR (\"modified a simulation algorithm\"))".
• Removing quotes may allow a broader search: (( modified adamdaptive estimation algorithm ) OR ( modified a simulation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adamdaptive estimation algorithm") OR ("modified a simulation algorithm"))*.
