From knowledge encoding to procedural generation for early-stage layout design: A case of linear shopping centres by Baizhou Zhang, Biao Li

“…The generative rules integrate the shopping centre layout's spatial patterns and geometric features and incorporate user-specified interaction parameters to form a generation tool prototype for early-stage layout design. The results show that the method can deal with the complex spatial elements of linear shopping centres and provide design references for architects, which helps combine generative algorithms with the design process.…”

Enhanced method based on virtual registers rotation by Yan PAN, Wei LIN

“…Sematic attacks based on the data flow analysis bring big challenges to the code obfuscation.Concerning the data flow of virtual machine based (VM-based) code protection,the method transfers the mapping relation between the virtual registers and the op-code of the bytecode during executing,which means the uncertainty and complexity of the data flow during interpretive execution of the bytecode.In addition,three policies are proposed to address the problem that how to choose the length of rotation for each bytecode,which grows complexity of the protection.Finally,a prototype of VRR-VM (virtual machine protection system based on virtual registers rotation) was implemented.Experiment results show that the method is effective and applicable for anti-reversing.…”
