Perhaps you should try some spelling variations:
"modified staffing optimization algorithm" » "modified staffing optimization algorithms", "modified staffing optimisation algorithm", "modified staffing estimation algorithm", "modified caging optimization algorithm"
"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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified staffing optimization algorithm\") OR (\"modified adaptive quantization algorithm\"))~".
• Removing quotes may allow a broader search: (( modified staffing optimization algorithm ) OR ( modified adaptive quantization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified staffing optimization algorithm") OR ("modified adaptive quantization algorithm"))*.
