Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective optimisation algorithm"
"machinery using source algorithm" » "machinery using our algorithm", "machinery using search algorithm", "machines using source algorithm", "machinery using force algorithm", "machinery using morse algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified multiobjective estimation algorithms\") OR (\"machinery using source algorithm\"))~".
• Removing quotes may allow a broader search: (( modified multiobjective estimation algorithms ) OR ( machinery using source algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective estimation algorithms") OR ("machinery using source algorithm"))*.
