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