Compared best results for the Pressure Vessel optimization problem reported by a large set of research papers validating Nature inspired search algorithms

This dataset contains an exhaustive list of references related to a well-known engineering design case: the pressure vessel problem. It has been repeatedly used as a reference case for validating a large number of nature inspired optimization algorithms.<br>The dataset contains not only the complete bibliographic references of 55 papers dealing with this engineering design case, but also the best results obtained in the numerical analysis performed on those research works. Detailed tracking of all values corresponding to the cost function and constraints fulfilments or violations are also included.The tab separated text file contains the following columns:<br>Columns 1 to 7 (bibliographic reference data)<b>Full reference</b> | <b>Journal </b>| <b>Year </b>| <b>Authors </b>| <b>Search algorithm inspiration</b> |<b>Acronym </b><br><br>Columns 8 to 11 (values of the design variables for the reported best configuration, thickness of shell and cylinder, radius of cylinder and length of cylinder)<b>x₁ </b> (Ts) | <b>x₂ </b> (Th) | <b>x₃ </b> (R) | <b>x₄ </b> (L) <br><br>Column 12 (value of the cost function calculated by the author of this dataset according to the design variables reported by the authors of each paper and presented in columns 8 to 11)<b>f(X)</b><br><br>Columns 13 to 17 (flags indicating which constraints are violated when using the reported values of the design variables) <b>g₁ </b>| <b>g₂ </b>| <b>g₃ </b>| <b>g₄ </b>| <b>T</b> <br>(it is assumed that a constraint is not fulfilled if the expected value is exceeded in more than 0.0001 or the thickness of plates does not follow the problem's definition)<br>Columns 18 and 19 (valid values of the cost function and value of that cost reported by the paper's authors)<b>Valid value </b>| <b>reported f(X)</b><br>Columns 20 to 23 (values of each constraint result calculated using the reported values of the design variables presented in columns 8 to 11)<b>g1 </b>| <b>g2 </b>| <b>g3 </b>| <b>g4</b><br>
