Perhaps you should try some spelling variations:
"surface functionals in coding program" » "surface functional in coding program" (Expand search), "surface functionalised in coding program" (Expand search), "surface functionality in coding program" (Expand search), "surface functions in coding program" (Expand search), "surface functional index coding program" (Expand search), "surface functionals in cloning program" (Expand search), "surface functionals in loading program" (Expand search), "surface functionals in cooling programs" (Expand search), "surface functionals on coding program" (Expand search), "surface functionals in decoding program" (Expand search), "surface functionals non coding program" (Expand search)
"advanced data coding packing problem" » "advanced data cutting packing problem" (Expand search), "advanced data chain packing problem" (Expand search), "advanced data aging packing problem" (Expand search), "advanced age coding packing problem" (Expand search), "advanced and coding packing problem" (Expand search), "advanced data cloning packing problem" (Expand search), "advanced data recording packing problem" (Expand search), "advanced data crossing packing problem" (Expand search), "advanced data coding packing problema" (Expand search), "advanced data coding packing problemas" (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: "((\"surface functionals in coding program\") OR (\"advanced data coding packing problem\"))~".
• Removing quotes may allow a broader search: (( surface functionals in coding program ) OR ( advanced data coding packing problem ))~.
• Adding a wildcard symbol may retrieve word variants: (("surface functionals in coding program") OR ("advanced data coding packing problem"))*.
