In last article I have mention some about few ways to encode problem. Now I just want to explain more about one of the method that what I be use which is Permutation Encoding.
Permutation encoding can be used in ordering problems, such as traveling salesman problem or task ordering problem. In permutation encoding, every chromosome is a string of numbers, which represents number in a sequence.
In my research I use permutation where it can give order chosen node to be sleep mode, than monitor the delay on network as it fitness. Time slot of node to be sleep mode will be change for each chromosome population if packet delay of network increase. The process will be repeated until one solution have been found.
(1 2 3 4 5 6 7 8 9) Chromosome A +
(4 5 3 6 8 9 7 2 1) Chromosome B
=> (1 2 3 4 5 6 8 9 7) After crossover
(1 2 3 4 5 6 8 9 7) => (1 8 3 4 5 6 2 9 7)

- Binary Encoding
- Permutation Encoding
- Value Encoding
- Tree Encoding
Under this process also have 3 methods where:
- Roulette Wheel
- Tournament Selection
Under this process also have many methods but 2 of them are:
- Exponential Scaling
- Linear Normalize
Under this process just similar between all researchers that using GA
Under this process it will select the best population for next iteration, so if there are new child cromosome that better with their parent cromosome from previous generation then it will replace or overwrite that parent cromosome.

- Encoding of the problem in binary string.
- Random generating of a population. This one includes a genetic pool representing a group of possible solution.
- Reckoning of a fitness value for each subject. It will directly depend on the distance of optimum.
- Selection of the subjects that will mate according to their share in the population global fitness.
- Genomes crossover and mutations.
- And then start again from point 3.
For now I need to try some example that related with GA. My focus now is understanding the GA operation itself and to know how GA can help me using optimization method to find my solution. Example each node that I need to force to sleep mode will represent by a bit. Bit 1 represent a node in active mode and bit 0 will represent node that in sleeping mode. With this all bit representative can build one chromosome. With this chromosome it can start with GA operation that will come with new offspring. This new offspring can be test with a formula or simulation that can give result where it was good chromosome or bad chromosome.

Last week I received a letter from Chair of Research of NTU, wrote like this:
Dear Mohd Taufiq
Attached please find the scan copy of the approved letter.
The Original Copy has been sent to you via normal airmail.
Please keep a close look out then.

This is my great opportunity to study at oversea, I mean even do Singapore is just very near to Malaysia, since it was not Malaysian, can be assume at oversea level. It's ok better than nothing right ...

As student sponsor by NSF, I was allowed to do attachment at any other University to get more experience and increase learning curve during studies. For master student we are allow only at Malaysia and Singapore Univ. only while for PhD student unlimited to any Univ. in the world. I do some finding on University at Singapore. There are NUS and NTU. So I choose NTU because this university more focus on technology area compare with NUS.

- By using Notepad++ software open that trace file.
- Then open find & replace menu.
- Select regular expression search mode. See figure attach
- Then at find what: type \[ pt . \]
- For replace with: leave it empty
- Replace all
- Dont forget to save your file
Your trace file now can open using tracegraph

Some sort like this:
∑ sleep time = Time last node sleep - Time 1'st node sleep
Time node i wake up = Time node i sleep + ∑ sleep time
Then the result change where new method can save more energy compare with other routing protocol.
