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

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

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