Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm", "modified _daptive quantization algorithm", "modified dfdaptive quantization algorithm", "modified adamdaptive quantization algorithm"
"modified a simulation algorithms" » "modified a estimation algorithms", "modified a optimization algorithms", "modified a estimation algorithm", "modified _ simulation algorithms", "modified df simulation algorithms", "modified adam simulation algorithms"

Try widening your search to All Fields.

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

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