question: public void randomInit ( ) { do { m_bits = new boolean [ m_nNodes * m_nNodes ] ; for ( int i = 0 ; i < m_nNodes ; i ++ ) { int iPos ; do { iPos = m_random . nextInt ( m_nNodes * m_nNodes ) ; } while ( isSquare ( iPos ) ) ; m_bits [ iPos ] = true ; } } while ( hasCycles ( ) ) ; calcGlobalScore ( ) ; }
target:  initialize with a random structure by randomly placing m_nNodes arcs.
