Perhaps you should try some spelling variations:
"modified allocation optimization algorithmss" » "modified allocation optimization algorithms", "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified location optimization algorithmss"
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified adaptive quantization algorithm") OR ("modified allocation optimization algorithmss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive quantization algorithm\") OR (\"modified allocation optimization algorithmss\"))*".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) OR ( modified allocation optimization algorithmss ))*.
