Defining specific arcs

 
tex2html_wrap_inline33790 tex2html_wrap_inline33790 Syntax

BD>arc : B tex2html_wrap_inline33794 , B tex2html_wrap_inline33798 , A tex2html_wrap_inline33712

where tex2html_wrap_inline34754 and tex2html_wrap_inline34756 are the names of elements or bases. A is an integer.

The ARC:  command is used to specify or redefine arcs between two given nodes tex2html_wrap_inline35092 and tex2html_wrap_inline35094 on an influence diagram. The arc type is given by the integer A, which should be an integer constructed from the bits discussed in Table 11.4. Any pre-existing definition of an arc between tex2html_wrap_inline35092 and tex2html_wrap_inline35094 is overwritten. In particular, if A=0, meaning no arc between tex2html_wrap_inline35092 and tex2html_wrap_inline35094 then the former arc definition, if any, is deleted.

The ARC:  command can be used in combination with the GRID0:  command to generate influence diagrams with a small number of arcs. The autoarc  control can be used to have [B/D] draw arcs automatically. See §20.9 for details.
