We used a charting the field approach by classifying articles based on research topic, method research, research population and external or internal factors that affect the sustainability report. The results of this study indicate that research topics discussing the linkages between financial performance and sustainability reporting in Indonesia have been extensively researched but still show inconsistencies in research results, so they need to be studied further. Furthermore, we also found that quantitative research methods, analytical research methods, public company populations and internal factors that influence sustainability reporting were the most tested by researchers.</span></p> Rizky Yuniar Sururi, Evi Gantyowati ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://j.ideasspread.org/index.php/jems/article/view/1194 Mon, 01 May 2023 00:00:00 +0800 https://j.ideasspread.org/index.php/jems/article/view/1207 <p>The paper considers various aspects and approaches regarding the search for a system of differenrt representatives (<em>SDR</em>) of subsets of a finite set. Algorithm 3 has been developed, which is an algorithmization of the search process for <em>SDR</em> on the basis of Hall's theorem on the existence of <em>SDR</em>. Algorithms 1-5 for searching for partial and complete <em>SDRs</em> based on the technology for solving problems of the transport type, in particular, the algorithm associated with the construction of cycles, are given. <em>SDR</em> search algorithms can be used as auxiliary tools for solving combinatorial problems. It is also shown, conversely, that the search for <em>SDR</em> can be considered as a combinatorial optimization problem.</p> <p>Mathematics Subject Classification – MSC2020: 90-08, 90B06, 90C27</p> Dmitri Terzi ##submission.copyrightStatement## http://creativecommons.org/licenses/by/4.0 https://j.ideasspread.org/index.php/jems/article/view/1207 Wed, 07 Jun 2023 00:00:00 +0800
