Perhaps you should try some spelling variations:
"covariance function and coding program" » "covariance functions and coding program" (Expand search), "ovarian function and coding program" (Expand search), "covariance function and cloning program" (Expand search), "covariance function and loading program" (Expand search), "covariance function and cooling programs" (Expand search), "covariance function and coping program" (Expand search), "covariance function and cooling program" (Expand search), "covariance function and cooking program" (Expand search)
"based distributed processing coding program" » "and distributed processing coding program" (Expand search), "based distributed processing decoding program" (Expand search), "based distributed processing cooling program" (Expand search), "based distributed processing according program" (Expand search), "based distributed processing cloning program" (Expand search), "based distributed processing loading program" (Expand search), "based distributed processing cooling programs" (Expand search)

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("covariance function and coding program") OR ("based distributed processing coding program"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"covariance function and coding program\") OR (\"based distributed processing coding program\"))".
• Removing quotes may allow a broader search: (( covariance function and coding program ) OR ( based distributed processing coding program )).
• Adding a wildcard symbol may retrieve word variants: (("covariance function and coding program") OR ("based distributed processing coding program"))*.
