Perhaps you should try some spelling variations:
"modified a simulation algorithms" » "modified a estimation algorithms", "modified a optimization algorithms", "modified a solution algorithm", "modified _ simulation algorithms", "modified df simulation algorithms", "modified adam simulation algorithms"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive estimation algorithm") or ("modified a simulation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive estimation algorithm") OR ("modified a simulation algorithms")).
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithm ) or ( modified a simulation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithm") or ("modified a simulation algorithms"))*.
