Hello, <br><br>I may probably wrongly use the PPL's Java interface, but here are my naive questions among others,<br><br>1. Is it normal that the following codes raise this error " Invalid memory access of location 0x0 rip=0x1011a50ca " ? <br>
(The JAVA's interface for 'drop_some_non_integer_points" requies an integer or variable-set plus an integers as its parameters, rather than C's <br> " void drop_some_non_integer_points (Complexity_Class complexity=ANY_COMPLEXITY)" )<br>
.<br>.....cod<br> Constraint c = new Constraint(le_5Z, Relation_Symbol.GREATER_THAN, le_X);<br> Constraint_System cs = new Constraint_System();<br> cs .add(c);<br> NNC_Polyhedron ph2=new NNC_Polyhedron(cs);<br>
ph2.drop_some_non_integer_points(new Integer(1));<br>......<br><br>2. I don't find ways to specify a constraint with explicite rational or real numbers, like x>=2.5, because the 'Coefficient' only accepts integers. Does than mean that I am obliged to <br>
use 2 *x >=5 rather than x >2.5? <br><br>Thanks. <br>zell.<br>
