Perhaps you should try some spelling variations:
"modified dfdamdamdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdamdamdaptive estimation algorithm"
"modified a optimization algorithms" » "modified a optimisation algorithm", "modified a estimation algorithms", "modified a estimation algorithm", "modified _ optimization algorithms", "modified _ optimisation algorithms", "modified game optimization algorithms", "modified df optimization algorithms", "modified adam optimization 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 optimization algorithms") or ("modified dfdamdamdaptive quantization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified a optimization algorithms") OR ("modified dfdamdamdaptive quantization algorithm")).
• Removing quotes may allow a broader search: (( modified a optimization algorithms ) or ( modified dfdamdamdaptive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified a optimization algorithms") or ("modified dfdamdamdaptive quantization algorithm"))*.
