Release Notes for GAGA 1.1.0

The previous version, GAGA 1.0.0, remains available on www.gaga4cs.org.

New Algorithms
This release contains all previous algorithms:
  ThresholdSD
  ThresholdCG
  IHT
  NIHT
  HTP
  CSMPSP
This release contains the following new algorithms:
  CGIHT (including both CGIHT and CGIHTrestarted)
  CGIHTprojected
  FIHT
  1-ALPS(2)

New Options:
This release contains two new option pairs for gagaOptions.m:

 restartFlag - used with CGIHT
  options = gagaOptions('restartFlag','on') for CGIHTrestarted
  options = gagaOptions('restartFlag','off') for CGIHT
  (DEFAULT) is 'off'

 projFracTol - used with CGIHTprojected
  options = gagaOptions('projFracTol',value) where value is any positive number.
  (DEFAULT) is 3

Accelerated Dense-Sparse Matrix-Vector Multiplication
This release contains a new version of A_gen which exploits the 
fact that most multiplications involve a sparse vector.
This is located in Matrices/gen_gpu.cu.

New Noise Output File Name for noise_level=0
In the previous version, when generating data with noise the output
text file always ended with _noiseX.XXX.txt where X.XXX was the noise
level.  This was true even for noise_level=0.  In this version, if
noise_level=0, the output file does not have the _noise0.000 in the
file name.

New stopping criteria	
The algorithms now detect a cycle when the current residual norm is equal up 
to single precision to any of the previous 15 residuals.  This has no observed 
effect in the noiseless setting.  In the noise setting, this stopping criterion
generally terminates the algorithm.  This can be turned off for individual algorithms
in algorithms.cu by setting useCycleFlag = 0 in the initialization.  This is NOT
an option available for gagaOptions.
