It is my fault, but remember every time you write a program, do a systematic
test and produce a report to make sure that every point is correctly
implemented and tested.

Data mining projects are data and computing intensive ones, so it is important
to keep to as efficient as you can.
In project one, my program is a little slower than other people's program, I
think the main reason lies in that I failed to sorted each gene data during the
entropy calculation process, which will try all possible splits and find the
one with the highest information gain. So it is advisable that gene data be
sorted before being processed.
For project two, efficiency problem will be more critical, because if not
correctly processed, it will take longer time to process. So, be careful with
the algorithm implementations.

When creating a new object by using the new operator, always try to test if the
memory allocation is successful or not. Two methods can be used for this
purposes.
# use the std::nothrow to depress throwing exceptions.
# use the try {} catch(...) {} programming block so that the thrown exception objects can be caught.
