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