I am Pham Diep Chi, a PhD student from Viet Nam. I use PPL for my thesis research. I would like to ask you some question on PPL
I would like to print value of constraints (Constraint_System, C_Polyhedron, ...) on terminal, and i use print function but it does not show anything.
For example: i have Constraint_System cs, C_Polyhedron ph; i use print: cs.print(); ph.print();
they does not show their values on terminal (i use ubuntu OS); I try to use function: print_constraints() as you use in examples codes, but i always get error.
Dear Pham Diep Chi,
please write again to the ppl-devel@cs.unipr.it mailing list including a self-contained C++ source along with the compilation command you are using, a description of the result you expect and the output you obtain instead of what you would like to see.
Beside, Can i convert the value of contraint to string (text) and inverse? for example i have a constraint has value : a + b >=5 i would like to convert it to "a+b >=5". How do i convert like that.
For converting to a string, you can use the facilities made available by the <sstream> standard library header file. There are several examples in the PPL sources. For converting from a string, you need to define a syntax and then write a parser. Kind regards,
