Perhaps you should try some spelling variations:
"modified dfdaptive quantization algorithm" » "modified adaptive quantization algorithm", "modified dfdaptive estimation algorithm"
"modified a optimisation algorithm" » "modified a optimization algorithms", "modified a estimation algorithm", "modified a estimation algorithms", "modified _ optimisation algorithm", "modified _ optimization algorithm", "modified game optimization algorithm", "modified df optimisation algorithm", "modified adam optimisation algorithm"

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 dfdaptive quantization algorithm") or ("modified a optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified dfdaptive quantization algorithm") OR ("modified a optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified dfdaptive quantization algorithm ) or ( modified a optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified dfdaptive quantization algorithm") or ("modified a optimisation algorithm"))*.
