Perhaps you should try some spelling variations:
"modified charging optimized algorithm" » "modified charging optimized algorithms", "modified charging optimizer algorithms", "modified choosing optimizer algorithm", "modified caging optimized algorithm", "modified carbon optimized algorithm"
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive 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 charging optimized algorithm\") OR (\"modified adaptive estimation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified charging optimized algorithm ) OR ( modified adaptive estimation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging optimized algorithm") OR ("modified adaptive estimation algorithm"))*.
