Perhaps you should try some spelling variations:
"modified network optimisation algorithm" » "modified network optimization algorithms", "modified network estimation algorithm", "modified network estimation algorithms", "modified network optimization algorithm", "certified network optimisation algorithm", "defined network optimisation algorithm", "modified near optimisation algorithm"
"machinery using method algorithm" » "machinery using mom algorithm", "machines using method algorithm", "machinery nursing methods algorithm", "machinery focusing method algorithm", "machinery using metal algorithm"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("machinery using method algorithm") OR ("modified network optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( machinery using method algorithm ) or ( modified network optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("machinery using method algorithm") or ("modified network optimisation algorithm"))*.
