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 method algorithm" » "machines using mom algorithm", "machinery using method algorithm", "machines nursing methods algorithm", "machines focusing method algorithm", "machines using metal 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 method algorithm") OR ("modified allocation optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machines using method algorithm\") OR (\"modified allocation optimisation algorithm\"))".
• Removing quotes may allow a broader search: (( machines using method algorithm ) OR ( modified allocation optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machines using method algorithm") OR ("modified allocation optimisation algorithm"))*.
