Perhaps you should try some spelling variations:
"shape optimization python python programming" » "shape optimization method python programming" (Expand search), "shape optimization option python programming" (Expand search), "shape optimization methods python programming" (Expand search), "the optimization python python programming" (Expand search), "shape optimization pythons python programming" (Expand search), "shape optimization piton python programming" (Expand search), "shape optimization pitons python programming" (Expand search)
"coder diffusion of coding program" » "copper diffusion of coding program" (Expand search), "order diffusion of coding program" (Expand search), "node diffusion of coding program" (Expand search), "coder diffusion of cloning program" (Expand search), "coder diffusion of loading program" (Expand search), "coder diffusion of cooling programs" (Expand search), "coder diffusion non coding 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: "((\"coder diffusion of coding program\") OR (\"shape optimization python python programming\"))~".
• Removing quotes may allow a broader search: (( coder diffusion of coding program ) OR ( shape optimization python python programming ))~.
• Adding a wildcard symbol may retrieve word variants: (("coder diffusion of coding program") OR ("shape optimization python python programming"))*.
