Perhaps you should try some spelling variations:
"modified caging optimization algorithm" » "modified caging optimization algorithms", "modified caging optimisation algorithm", "modified caging estimation algorithm", "modified staffing optimization algorithm"
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation 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 caging optimization algorithm") OR ("modified notion estimation algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified caging optimization algorithm\") OR (\"modified notion estimation algorithms\"))".
• Removing quotes may allow a broader search: (( modified caging optimization algorithm ) OR ( modified notion estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified caging optimization algorithm") OR ("modified notion estimation algorithms"))*.
