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...

The objective of this study was to evaluate the possibility of using treated industrial by-products as a zinc (Zn) source and compare their Zn availability and efficiency to ZnSO4. A greenhouse factorial experiment in a completely randomized block design was conducted with corn (Zea mays L.) in triplicates. Treatments included three Zn sources (ZnSO4, IUT-UT in size of < 1 mm and IUT-UT in size...
