Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"machines using source algorithm" » "machines using our algorithm", "machines using search algorithm", "machinery using source algorithm", "machines using force algorithm", "machines using morse 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 source algorithm") OR ("modified multiobjective optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machines using source algorithm\") OR (\"modified multiobjective optimisation algorithm\"))*".
• Removing quotes may allow a broader search: (( machines using source algorithm ) OR ( modified multiobjective optimisation algorithm ))*.
