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