<p>Good Evening to everyone,</p>

<p>I'm trying to achieve the less expensive construction material, with the problem of satisfy structural verifications (1 fitness for any of these, like stress in the beam must not exceed the elastic value, ecc..).

<p>Good Evening to everyone,</p>
<p>I'm writing here because I'm trying to optimize a girder bridge for my thesis.</p>
<p>I'm trying to achieve the less expensive construction material, with the problem of satisfy structural verifications (1 fitness for any of these, like stress in the beam must not exceed the elastic value, ecc..). Now, my problem is that, since I know that a solution with 3 beam of specific dimension and another solution of 4 beam with smaller dimension of the other, can be the same in terms of cost and tension, I obtain a huge pareto front solution. </p>
<p>At this point I don't really know how to proceed because, I need to find the "best" solution in terms of cost that minimize every subtraction verification simultaneously. </p>
<p></p>
<p>Any idea?</p>
<p>Thank you in advance.</p>

<p>Leonardo</p> Automatically run solver and output best solution after N generationstag:www.grasshopper3d.com,2018-11-09:2985220:Topic:19440242018-11-09T22:09:50.051ZMax Marschallhttps://www.grasshopper3d.com/profile/MaxMarschall
<p>Below is a schematic of what I want to do, namely:</p>

<li>Trigger a solver like Octopus or Galapagos from within a definition (not by double-clicking the component), run the solver for a fixed number of generations, then only output the best solution (I only have 1 evaluation metric)</li>

<p></p> Gene pool and Heteroptera's gene pool controllertag:www.grasshopper3d.com,2017-01-22:2985220:Topic:16761612017-01-22T13:24:59.892ZClaudio Campanilehttps://www.grasshopper3d.com/profile/ClaudioCampanile
<p>Hi</p>
<p></p>
<p>I am using heteroptera gene pool controller to change the dimension of the gene pool if I want to run the definition for a (u,v) array of urban blocks. The array stays the same during the simulation, but I need to do simulations for different arrays. Thus, I used Heteroptera's gene pool controller to modify their length and other characteristics.</p>

<p>I have been experimenting an optimization coupled with HB&LB, however in the end of the whole process, the Rhinoceros crashes. Consequently, the Grasshopper also need to be closed which also causes the loss of all Octopus results. What I need is the non-dominants in the end. Unfortunately, auto save file doesn’t have the Octopus results either. <br></br> <br></br> Has anybody experienced such failure like this?

<p>Does anyone know how can I start running Octopus 0.2?</p>
<p>I know in version 0.1 we should double click on the component, in 0.2 double clicking does open any window.</p>
<p></p>
<p>Any help will be appreciated.</p>

<p>Hi,</p>
<p></p>
<p>I just set up my first simulation using Octopus and have some basic questions how to progress. I am really sorry that questions are basic and straightforward to most of you but I would appreciate a reply. </p>

<p>Hi,</p>
<p></p>
<p>I just set up my first simulation using Octopus and have some basic questions how to progress. I am really sorry that questions are basic and straightforward to most of you but I would appreciate a reply. </p>
<p></p>
<p><span style="font-size: 13px;">Q1. I run two generations in my generation 0 I can distinguish 3 lines...what do they refer to? I got my Fitness as 5 values Heating, Cooling</span> <span class="GINGER_SOFATWARE_correct" style="font-size: 13px;">etc</span> <span style="font-size: 13px;">and thought there will be 5 lines </span></p>
<p>Q2. What are values on X/Y/Z axis and color legend? What colors <span class="GINGER_SOFATWARE_correct">means</span> I got <span class="GINGER_SOFATWARE_correct">black</span> 409.87 and red 33.63 <span class="GINGER_SOFATWARE_correct">amd</span> <span class="GINGER_SOFATWARE_correct">tis</span> dot 99.2:5 and green 2.27:4?</p>
<p><span style="font-size: 13px;">Q3. I can see that in every generation my values are condensed ...of course I shall run this for many more generations... <span class="GINGER_SOFATWARE_correct">but</span> as <span class="GINGER_SOFATWARE_correct">result</span> of my simulation which <span class="GINGER_SOFATWARE_correct">is <span class="GINGER_SOFATWARE_correct">minimize</span></span> <span class="GINGER_SOFATWARE_correct">energy will be the last one that head down?</span> </span></p>
<p><span style="font-size: 13px;">Q4. I was reading this forum and there is no</span> <span class="GINGER_SOFATWARE_correct" style="font-size: 13px;">current way of savings all <span class="GINGER_SOFATWARE_correct">results</span> for each run ?</span></p>
<p><span style="font-size: 13px;">Q5. If there are some any general <span class="GINGER_SOFATWARE_spelling">advice</span> how I shall <span class="GINGER_SOFATWARE_correct">tackle</span> my problem this would be great!</span></p>
<p>Ps. I will try to run this example over the weekend to see what is the result.</p>
