_D_e_s_c_r_i_p_t_i_o_n:

     'EM_internal' is the internal function called by 'EM' .

_U_s_a_g_e:

     EM_internal(demand = demand, eps = 0.005)

_A_r_g_u_m_e_n_t_s:

  demand: demand vector with constrained and unconstrained entries. A 0
          in the name of an entry means that the corresponding demand
          is unconstrained. Conversely, a 1 in the name of an entry
          suggests that the corresponding demand is constrained. 

     eps: small number used as the stopping criterion. The default
          value is 0.005.

_D_e_t_a_i_l_s:

     'EM_internal' unconstrains demand data in quantity-based revenue
     management.

_V_a_l_u_e:

   param: parameters of demand distribution 

   niter: number of iterations 

  demand: unconstrained demand 

 history: convergence history
