Visualizing Near Optimal Solution for Rubik’s Cube Problems in 2D and 3D Models

Solving the Rubik’s cube is a challenging task. It can start from any face with any move. Finding the minimum number of moves in solving Rubik’s cube problem can be considered as NP-hard problem. Both the size of the solution space induced by the number of attainable states and multiple desirable side-objectives next to restoring the cube, in the least possible number of steps and lowest complexity, makes this an interesting optimization problem.
Ant colony system which is a variant of ant colony optimization is proposed to solve the Rubik’s cube problem. The ant algorithm is one of the most suitable meta-heuristic algorithms to find a good solution in reasonable time and resource. As characterized, Ant Colony Optimization meta-heuristic, uses groups of simple agents, modeled as artificial ants, to find optimal length trails through problem graphs Ant colony system algorithm has the ability to extend the number of ants on different face of the cube to explore many solutions in parallel mode. Local and global pheromone updates can be also applied in the process to obtain the near optimal solution.
In this presentation, a near optimal solution of rubik’s cube problem using ant colony optimization will be presented by visualizing it in 2D and 3D rubik’s cube models.
Keywords:- Rubik’s Cube, Ant colony Algorithm, Optimal solution,  meta-heuristic algorithms, ACO.

Toward Green and Health Environment: An Effective Solution for Eliminating Computers and Electronics Waste

In last few decades; Computers and electronic devices production and consumption has grown rapidly. Although such devices have greatly improved our quality of life but it also created a big environmental problem called electronic waste (e-waste). Studies show that millions of tons of garbage generated yearly as e-waste world-wide. The E-waste is more toxic and harmful than normal household garbage. Studies show that E-waste is growing rapidly compared to other household waste. Computers and electronic waste contain toxic heavy metals, including arsenic, antimony, lead, mercury, nickel and zinc. It is estimated that about 40% of all heavy metals in household garbage comes from electronic equipment. 

The UN estimates about 50 million tons of e-waste may be generated in world yearly, but small percentage of it are recycled. Incomplete technology, competitions between electronic production companies, and lake of morality leads to agile products with small change in term of functionality or design; Mobile phones with new multi-functions, ever lighter notebooks and flatter TV screens are quickly replacing outdated products. This was associated with heavy announcements in different media which affected not small ratio of customers. As the consumption of electronics has boomed, so have the waste amounts generated by discarded products. 

New EU legislation requires that the cost of properly disposing of electronic products must be picked up by the producers of the waste (manufacturers, retailers, branders and importers). Consequently, creative minds at several electronics companies have been set in motion aimed at producing more eco-friendly products that are easier to recycle and handle when they reach their end-of-life. This positive EU trend will have global effects, since the electronics market and production process is global.

However, several developing countries in Asia, Africa and Latin America suffer from lack of proper systems for recycling and disposal treatment experience; this leads to increase e-waste problems because of increasing consumption of electronics in these countries at present as well as they become a hub for e-waste exported from the industrial world to developing nations. UNEP (2009) and other studies show that in informal recycling in countries such as China, India, Ghana, Nigeria, and Mexico; workers are exposed to hazardous chemicals and material when products are broken apart to extract valuable content. On the other hand the water, air and soil are also polluted.

This analytical study for status of E-Waste (based on statistics in several counties) proposes an effective guidance solution to eliminate and control e-waste as well as protecting workers’ health and environment especially in developing world. This leads to have a green and healthy environment.

Keywords: Computer waste, e-waste, waste elimination, e-waste recycle, green environment.
