$Id: sgb2alt-doc.txt,v 1.1 1996/10/04 13:29:27 ewz Exp $ Name: sgb2alt Function: converts from sgb format to alternative format. Usage: sgb2old Details: The alternative format is as follows: GRAPH (#nodes #edges id uu vv ww xx yy zz): [all integer utility fields] VERTICES (index name u v w x y z): 0 [all integer utility fields for node0] 1 [all integer utility fields for node1] .... EDGES (from-node to-node length a b): [all integer utility fields] .... For example, here is a 10 node graph represented first in SGB file format and then in the alternative format. (Note that the SGB format is not intended to be easily read by humans.) ------------------------- SGB Format Starts Here -------------------------- * GraphBase graph (util_types ZZZIIZIZIZZZZZ,14V,102A) "geo(0,{10,10,3,0.200,0.500,0.500})",10,28,10 * Vertices "0",A4,3,4 "1",A6,8,6 "2",A8,7,6 "3",A14,6,0 "4",A18,8,1 "5",A22,0,3 "6",A17,4,0 "7",A24,3,6 "8",A26,1,5 "9",A27,7,2 "",0,0,0 "",0,0,0 "",0,0,0 "",0,0,0 * Arcs V2,0,4,0 V0,0,4,0 V4,A0,6,0 V0,0,6,0 V9,A2,4,0 V0,0,4,0 V8,0,7,0 V1,0,7,0 V6,A1,7,0 V2,0,7,0 V5,0,7,0 V3,0,7,0 V8,A10,7,0 V3,A7,7,0 V9,A12,2,0 V3,A5,2,0 V6,A3,4,0 V4,A9,4,0 V7,A16,7,0 V4,0,7,0 V7,A11,4,0 V5,A19,4,0 V9,A20,7,0 V5,A15,7,0 V9,A21,6,0 V7,A23,6,0 V9,A13,7,0 V8,A25,7,0 0,0,0,0 [NOTE: 70 lines of 0,0,0,0 deleted] 0,0,0,0 0,0,0,0 0,0,0,0 * Checksum 1029917895 ---------------- SGB Format Ends Here; Alternative Format Starts Here ----------------- GRAPH (#nodes #edges id uu vv ww xx yy zz): 10 28 geo(0,{10,10,3,0.200,0.500,0.500}) 10 VERTICES (index name u v w x y z): 0 0 3 4 1 1 8 6 2 2 7 6 3 3 6 0 4 4 8 1 5 5 0 3 6 6 4 0 7 7 3 6 8 8 1 5 9 9 7 2 EDGES (from-node to-node length a b): 0 9 4 0 0 4 6 0 0 2 4 0 1 8 7 0 2 6 7 0 3 9 2 0 3 8 7 0 3 5 7 0 4 7 7 0 4 6 4 0 5 9 7 0 5 7 4 0 7 9 6 0 8 9 7 0 ------------- Alternative Format Ends Here -----------------------------------------
