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