Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization 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 notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines using source algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( machines using source algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines using source algorithm") or ("modified notion optimization algorithms"))*.
