Perhaps you should try some spelling variations:
"modified adaptive estimation algorithmsss" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive ventilation algorithmsss", "modified quantile estimation algorithmsss", "modified adaptive quantization algorithmsss", "modified passive estimation algorithmsss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective 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 objective optimization algorithm\") OR (\"modified adaptive estimation algorithmsss\"))~".
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) OR ( modified adaptive estimation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") OR ("modified adaptive estimation algorithmsss"))*.
