<div> </div>
<div>
<div style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">my name is Natalie and I study at the Johannes Gutenberg University in Mainz.</div>
<div style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">Currently I am writing my Bachelor Thesis at the chair in logistikmanagement about " Models for the cutting stock- and bin packing problem".</div>
<div style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">Main focus of my Thesis is to implement selected models using SCIP/ZIMPL.</div>
<div style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;"> </div>
<div style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">I already implemented 2 models and it works perfectly:).</div>
<div style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">But <span style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">I have a problem to do </span>the last model (Gilmore & Gomory/ see PDF p. 4) <span style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">more dynamic.</span></div>
</div>
<div>I put it in ZIMPL and it works like I did it ( very static :S) (see gilmore.zpl). <span style="font-family: Verdana;font-size: 12.0px;line-height: 19.2px;">I determined t</span>he combinations of the feasible Cutting Pattern first ( line 25-32) (see PDF Cutting Pattern) and pretended we know how many efficient cutting pattern we´ve got (line 6).</div>
<div>But actually I want ZIMPL to generate the combinations (line 25-32) and after that to count how many Cutting Pattern we are looking at ( line 6). </div>
<div>Is this eaven possible to do in ZIMPL and if yes HOW :D? I really tried my best, but unfortunately I couldn´t implement it. So I really hope you can help me implement it.</div>
<div> </div>
<div>I really appreciate your help.</div>
<div>Thanks in advance.</div>
<div> </div>
<div>Best,</div>
