Abstract

Dear Readers-This issue SNE 28(2) presents very interesting contributions, for instance the first Project Note contribution, and a Benchmark Note contribution of new style. SNE Volume 28 started offering the Project Note contribution for publication of project work, either as summary, or as report for (parts of) results, or as sketch of ongoing work, also aiming for discussion and feedback. Back in 1990, SNE started with publication of one-(and later two-) page solutions of the ARGESIM Benchmarks. In 2017, the publication possibilities for benchmark solutions have been extended. Depending on the benchmark, three types of 'solutions' can be submitted: i) a Benchmark Solution with concise description of model implementation and experimentation tasks (2 pages), ii) a Benchmark Report with sufficient detailed description of model implementation with variants and adequate experiment formulations (4-6 pages), and iii) a Benchmark Study presenting e.g. alternative or comparative modelling approaches and sketching analysis variants or supplemental model experiments (6-10 pages). This issue also continues with Vlatko eri 's algorithmic art as design for SNE cover pages. At right the cover pictures for SNE 28(1) and SNE 28(2) from the series BIRTH-the technique used is mapping and overlapping of squares emerging from a centre and fading out in colour. I would like to thank all authors for their contributions to SNE 28(2) showing the broad variety of simulation. And thanks to the editorial board members for review and support, and to the organizers of the EUROSIM conferences for cooperation in post-conference contributions. And last but not least thanks to the SNE Editorial Office for layout, typesetting, preparations for printing, with special thanks for support cooperation with Vlatko eri .
