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