Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion estimation algorithms", "modified notion estimation algorithm", "modified notion optimized algorithms", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified changing optimisation algorithm" » "modified changing estimation algorithm", "modified changing estimation algorithms", "modified staffing optimization algorithm", "modified caging optimisation 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 changing optimisation algorithm") OR ("modified notion optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified changing optimisation algorithm\") OR (\"modified notion optimization algorithms\"))*".
• Removing quotes may allow a broader search: (( modified changing optimisation algorithm ) OR ( modified notion optimization algorithms ))*.
