Solving Rubik’s cube means making a given cube to have each cube-face with one color, either of green, white, blue, yellow, orange, or red by rotating planes of the cube. ‘God’s number 20’ found in 2010 showed that any cube configuration can be obtained by less than or equal to 20 moves from the one-face one-color configuration. However, due to the enormous size of state space of cube, many researchers are still interested in computing the minimum length of move sequence for a given cube configuration. With the same reason, all cube patterns cannot be input to pattern database. Thus, there is a limit for computing the minimum length of solution move sequence by using cube pattern database. As the first step to develop a cube solution system utilizing cube pattern database, we implement a cube solution algorithm before utilization of pattern DB. After defining a class for the data and operations of the cube, we implement methods according to a beginner’s cube solution guide step by step into the class. Our cube solution system solves a given configuration by changing the up-front edge in 24 ways and produces one move sequence for each case. The answer of our cube solution system for a given configuration is one of the sequences with the shortest length which are obtained by shortening the produced sequences for the configuration. In addition, we observe the length of move sequence at each step, and compare the length to the one of existing solution.

A Fridrich-Petrus based 3×3×3 Classic Cube Solver
Marcelo T. Regalado Jr 대한전자공학회 2010 ICEIC:International Conference on Electronics, Inf Vol.1 No.1
The Three by Three by Three (3×3×3) Rubik’s cube is a mechanical puzzle that is popular at this point in time. But despite of its popularity, many cube users are still having a hard time solving the cube. The main objective of this proposed study is to create a userfriendly application that would be a big help to anyone who wants to solve the cube properly, sequentially and easily. Through the analysis of the two existing algorithm namely Petrus and Fridrich Method, the researcher come up with the development of an algorithm that will improve the existing algorithm in terms of reducing the number movements made in order to solve the cube. By adapting the concept of spiral model as the system development life cycle and under going to an iterative process, the researcher was able to develop a new faster and accurate algorithm that will be implement in the 3×3×3 Rubik’s cube solver.

This study investigates the factors affecting the topology of Rubik’s cube mechanism (RCM) and presents the synthesis theory of RCM. First, the revolute axis symmetry of the RCM is described and analyzed, and the general expression needed for the revolute axis to meet the symmetry is introduced. Next, the symmetry expression of the revolute pair contact surface (RPCS) of the RCM is given. The intersection between the RPCSs is analyzed via the adjacency matrix, and the adjacency matrix characteristics are given along with the motion characteristics of RCM. After determining the RPCS intersection, its topology is studied. Finally, the synthesis theory of RCM is presented, and the synthesis process and flowchart are proposed. The regular hexahedron RCMs with different topological structures are obtained after applying the synthesis theory. Hence, the theory proposed in this study provides strong theoretical support for the synthesis of other new RCMs.

대통령직 인수위원회의 국정 어젠다 세팅 과정에 관한 미래전략 연구 – 3차원 미래예측 루빅스 큐브 시나리오 방법 중심 –
양수영(Sooyoung Yang) 미래학회 2016 미래연구 Vol.1 No.1
본 논문은 대통령직 인수위원회의 국정 어젠다 세팅 과정에 관한 대안적 미래전략을 제안하며 루빅스 큐브 시나리오 방법의 기능과 의미를 설명한 다. 주로 정책학에서 연구되어 온 기존 정책의제설정 모형 및 이론들은 차기 행정부로 인수되는 과정, 특히 대한민국 대통령직 인수위가 작동되는 전환 기에 최적화된 미래전략적 정책의제설정 방법론에 적용되어 복잡한 정치 현상을 설명하기에는 제약 사항들이 있는 것으로 연구되었다. 차기 행정부로 인수되는 과정에 있어 국정 어젠다 세팅의 필요성은 전환기의 중요한 당면 과제이며 이 과정에 적용될 수 있는 미래연구 기법을 토대로 한 방법론을 제안하는 것이 본 논문의 목표였다. 결과적으로 본 논문은 국정 어젠다 세팅 과정에서의 미래전략적 대안과 가능성을 논증하는 과정에서 루빅스 큐브 시나리오 방법의 활용 가능성을 모색하였다. This thesis proposes alternative future strategy of government administration agenda setting process by presidential transition committee and explains the function and significance of Rubik’s Cube Scenario method. It was researched that existing models and theory of policy agenda setting that was mainly researched from policy science has many limits on explaining the complex politic phenomena due to the fact that it was applied to future strategic policy agenda methodology that is optimized to period of the transition term when Korean presidential transition committee are operated. In terms of process of transition to the next term executive branch, necessity of government administration agenda setting is urgent problem of transition period, and the objective of thesis is to suggest a methodology based on method to research the future that can be applied to this process. Therefore, this thesis sought application potential of Rubik’s Cube Scenario method in the process of demonstrating the future strategic solution and potential in the process of government administration agenda setting.
