Class GoodOPBReader

java.lang.Object
  org.sat4j.reader.Reader

All Implemented Interfaces:

Serializable

public class GoodOPBReader
extends org.sat4j.reader.Reader
implements Serializable

This class is a quick hack to read opb formatted files. The reader skip commented lines (beginning with COMMENT_SYMBOL) and expect constraints of the form: [name :] [[+|-]COEF] [*] [+|-]LIT >=|<=|= DEGREE where COEF and DEGREE are plain integer and LIT is an identifier.
