Perhaps you should try some spelling variations:
"modified dfdaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive estimation algorithm"
"modified model solution algorithm" » "modified model evolution algorithm", "modified model convolution algorithms", "modified model evolutionary algorithm", "modified male solution algorithm", "modified model solutions algorithm", "modified nodal solution algorithm", "modified model selection 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 dfdaptive estimation algorithm\") OR (\"modified model solution algorithm\"))~".
• Removing quotes may allow a broader search: (( modified dfdaptive estimation algorithm ) OR ( modified model solution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified dfdaptive estimation algorithm") OR ("modified model solution algorithm"))*.
