Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"machines using methods algorithm" » "machinery using methods algorithm", "machines nursing methods algorithm", "machines making methods algorithm", "machines counting methods algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("machines using methods algorithm") OR ("modified allocation optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machines using methods algorithm\") OR (\"modified allocation optimisation algorithm\"))*".
• Removing quotes may allow a broader search: (( machines using methods algorithm ) OR ( modified allocation optimisation algorithm ))*.
