The conference was cancelled due to the COVID-19 pandemic. The 20 full papers presented together with 3 invited abstracts were carefully selected from 29 submissions. Topics covered range from mathematical foundations to applications as conceptual and methodological tools in computer science and beyond. 410 0$aTheoretical Computer Science and General Issues,$x2512-2029 ;$v12062 606 $aMachine theory 606 $aArtificial intelligence 606 $aComputer networks 606 $aComputer science 606 $aNumerical analysis 606 $aFormal Languages and Automata Theory 606 $aArtificial Intelligence 606 $aComputer Communication Networks 606 $aComputer Science Logic and Foundations of Programming 606 $aNumerical Analysis 615 0$aMachine theory. 615 0$aArtificial intelligence. 615 0$aComputer networks. 615 0$aComputer science. 615 0$aNumerical analysis. 615 14$aFormal Languages and Automata Theory. 615 24$aArtificial Intelligence. 615 24$aComputer Communication Networks. 615 24$aComputer Science Logic and Foundations of Programming. 615 24$aNumerical Analysis. 676 $a004.0151 702 $aFahrenberg$b Uli$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aJipsen$b Peter$4edt$4http://id.loc.gov/vocabulary/relators/edt 702 $aWinter$b Michael$c(Professor).$4edt$4http://id.loc.gov/vocabulary/relators/edt 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a996418217103316 996 $aRelational and Algebraic Methods in Computer Science$92201468 997 $aUNISA
