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