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