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"
"boiler forecasting method algorithm" » "boiler focusing method algorithm", "boiler forecasting mixed algorithm", "boiler forecasting mom algorithm", "bowler forecasting method algorithm"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("boiler forecasting method algorithm") or ("modified notion optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("boiler forecasting method algorithm") OR ("modified notion optimization algorithms")).
• Removing quotes may allow a broader search: (( boiler forecasting method algorithm ) or ( modified notion optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("boiler forecasting method algorithm") or ("modified notion optimization algorithms"))*.
