Developer Journal 82 - On Boost Serialization

I'm still working on loading a vector of floats. I don't know why it won't work. I had a look at the Boost Numerics Library but I couldn't make sense of it.

I'm now converting the float to a string, reducing the number of decimal points to five or less, and converting back to a float.

Didn't work.

I removed the decimal points and the number after that.


I kept the decimal point.


I kept the decimal point and one number after that.


Trying up to 4 decimal places.


Up to 3 decimal places.


Up to 2 decimal places.


Strange. So strange.

I placed 0.596109 in every vector position.


I'm tracking the min and max values as well as the min and max lengths.

min: 0.100061
max: 0.599588
minLength: 5
maxLength: 8

I placed 0.100061 into every vector position.


I placed 0.599588 into every vector position.



minBitProb 0.100000001
maxBitProb 0.600000024

I changed minBitProb and maxBitProb and that resulted in different min and max values.

minBitProb 0.0
maxBitProb 1.0

min: 0.000396741
max: 0.999969
minLength: 5
maxLength: 11


Strange. Serialization of the vector of floats only works if the genome has a maximum of two decimal points. Has to be enough for now.

Looks like I'm going to have to stick with two decimal points for now.
