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 simulation coding decoding program" » "advanced modulation coding decoding program" (Expand search), "advanced calculation coding decoding program" (Expand search), "advanced simulation loading decoding program" (Expand search), "advanced simulation according decoding program" (Expand search), "advanced simulation modeling decoding program" (Expand search), "advanced simulation coding welcoming program" (Expand search), "advanced simulation coding deworming program" (Expand search), "advanced simulation coding feeding program" (Expand search), "advanced simulation encoding decoding program" (Expand search), "advanced simulation reading decoding program" (Expand search), "advanced simulation joint decoding program" (Expand search), "advanced simulation coding decloning program" (Expand search), "advanced simulation coding deloading program" (Expand search), "advanced simulation coding decooling programs" (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 simulation coding decoding program\"))~".
• Removing quotes may allow a broader search: (( covariance function and coding program ) OR ( advanced simulation coding decoding program ))~.
• Adding a wildcard symbol may retrieve word variants: (("covariance function and coding program") OR ("advanced simulation coding decoding program"))*.
