Dear AmirHossein,

Thank you for your kindness. I have tried your suggestion before. I have used the gvpr tool which shows the statistics of graphs. Unfortunately, it shows that the graph has 17 nodes and 49 edges.

I have tried to model the same case study using mCRL2 specification language. It is OK and shows a graph with 17 nodes and 51 edges. The graph generated by mCRL2 is given in the attachment.

Regards,

Somayeh

Dear All,I am new in TLA+, and I have tried to model a simple specification, which is given below:-------------------------------- MODULE ACME ------------------------------ --

EXTENDS Integers

VARIABLES entry1, entry2

------------------------------------------------------------ -----------------

TypeOk == /\ entry1 \in {"e", "A", "B", "A_del", "B_del"}

/\ entry2 \in {"e", "A", "B", "A_del", "B_del"}

Init == /\ entry1 = "e"

/\ entry2 = "e"

add_A == IF (entry1 = "A") \/ (entry2 = "A")

THEN /\ UNCHANGED entry1

/\ UNCHANGED entry2

ELSE IF (entry1 = "e") \/ (entry1 = "A_del") \/ (entry1 = "B_del")

THEN /\ entry1' = "A"

/\ UNCHANGED entry2

ELSE

/\ entry2' = "A"

/\ UNCHANGED entry1

add_B == IF (entry1 = "B") \/ (entry2 = "B")

THEN /\ UNCHANGED entry1

/\ UNCHANGED entry2

ELSE IF (entry1 = "e") \/ (entry1 = "A_del") \/ (entry1 = "B_del")

THEN /\ entry1' = "B"

/\ UNCHANGED entry2

ELSE

/\ entry2' = "B"

/\ UNCHANGED entry1

take == IF entry1 = "A"

THEN /\ entry1' = "A_del"

/\ UNCHANGED entry2

ELSE IF entry1 = "B"

THEN /\ entry1' = "B_del"

/\ UNCHANGED entry2

ELSE IF entry2 = "A"

THEN /\ entry2' = "A_del"

/\ UNCHANGED entry1

ELSE IF entry2 = "B"

THEN /\ entry2' = "B_del"

/\ UNCHANGED entry1

ELSE /\ UNCHANGED entry1

/\ UNCHANGED entry2

Next == \/ add_A

\/ add_B

\/ take

\* Created Sun Jun 30 15:22:19 IRDT 2019 by soltaniI expect a graph with 17 nodes and 17*3 edges. I mean every node should have three outgoing edges. However, two of the nodes, named (/\ entry1 = "A"/\ entry2 = "B") and (/\ entry1 = "B"/\ entry2 = "A") have just two outgoing edges.Is there a way to get the complete graph!Regards,Somayeh
