Perhaps you should try some spelling variations:
"modified allocation optimisation algorithm" » "modified allocation optimization algorithm", "modified allocation optimization algorithms", "modified allocation estimation algorithm", "modified allocation estimation algorithms"
"boiler using method algorithm" » "boiler using mom algorithm", "powder using method algorithm", "boiler nursing methods algorithm", "boiler focusing method algorithm", "boiler using metal algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("boiler using method algorithm") or ("modified allocation optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("boiler using method algorithm") OR ("modified allocation optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( boiler using method algorithm ) or ( modified allocation optimisation algorithm ))*.
