In fact, Ballantyne syndrome may result from any factor causing severe hydrops fetalis. The diagnosis can be supported by sudden and rapid weight gain, severe edema, oliguria with albuminuria, blood pressure less than 140 mmHg and hemo...

there are many approaches for solving variety combinatorial optimization problems (np-compelete) that devided to exact solutions and approximate solutions. exact methods can only be used for very small size instances due to their expontional search space. for real-world problems, we have to employ approximate methods such as evolutionary algorithms (eas) that find a near-optimal solution in a r...
