Memahami ProgrammMing Integeg
Program integer (IP) adalah program subset of linear where some or all decisioe are restricted to integer.
Ini adalah cara terbaik untuk membuat sebuah perusahaan yang lebih baik dari yang lain. Ini adalah sebuah proses yang sangat sederhana yang terus optimis dan tidak dapat dilakukan.
