Perhaps you should try some spelling variations:
"modified network optimization algorithms" » "modified network optimisation algorithm", "modified network estimation algorithms", "modified network estimation algorithm", "certified network optimization algorithms", "defined network optimization algorithms", "modified near optimization algorithms"
"code forecasting mixed algorithm" » "code forecasting method algorithm", "code forecasting air algorithm", "_ forecasting mixed algorithm", "a forecasting mixed algorithm", "code forecasting driven algorithm", "code forecasting winner 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: (("code forecasting mixed algorithm") or ("modified network optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("code forecasting mixed algorithm") OR ("modified network optimization algorithms")).
• Removing quotes may allow a broader search: (( code forecasting mixed algorithm ) or ( modified network optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("code forecasting mixed algorithm") or ("modified network optimization algorithms"))*.
