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)
"advanced image coding decoding program" » "advanced image coding welcoming program" (Expand search), "advanced image coding deworming program" (Expand search), "advanced image coding feeding program" (Expand search), "advanced image encoding decoding program" (Expand search), "advanced image reading decoding program" (Expand search), "advanced image joint decoding program" (Expand search), "advanced image coding decloning program" (Expand search), "advanced image coding deloading program" (Expand search), "advanced image coding decooling programs" (Expand search), "advanced stage coding decoding program" (Expand search), "advanced age coding decoding program" (Expand search), "advanced imaging coding decoding program" (Expand search)

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"covariance function and coding program\") OR (\"advanced image coding decoding program\"))~".
• Removing quotes may allow a broader search: (( covariance function and coding program ) OR ( advanced image coding decoding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("covariance function and coding program") OR ("advanced image coding decoding program"))*.
