Perhaps you should try some spelling variations:
"modified a optimisation algorithm" » "modified a optimization algorithms", "modified a estimation algorithms", "modified _ optimisation algorithm", "modified _ optimization algorithm", "modified game optimization algorithm", "modified df optimisation algorithm", "modified adam optimisation algorithm"
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation algorithm", "modified _daptive estimation algorithm", "modified dfdaptive estimation algorithm", "modified adamdaptive estimation 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 a optimisation algorithm\") OR (\"modified adaptive estimation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified a optimisation algorithm ) OR ( modified adaptive estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified a optimisation algorithm") OR ("modified adaptive estimation algorithm"))*.
