NEWS/ChangeLog for hydroPSO
--------------------------

0.3-1-1	10-May-2013
        o Suggested package 'multicore' (subseded) was replaced by 'parallel'
        o 'hydroPSO: functions from the 'multicore' package were replaced by equivalent from the 'parallel' package (detectCores, mclapply)

0.3-1	10-May-2013
        o new 'SWAT2005.zip' file, with and updated tutorial for calibrating SWAT 2005, compatible with hydroPSO >= 0.3-0   
          The old zip file was renamed to 'SWAT2005_old.zip', which is compatible with hydroPSO <= 0.1-58
          The new 'SWAT2005.zip' file now includes a new 'swat2005.out' binary file, in order to allow running SWAT2005 in GNU/Linux machines
        o new 'MF2005.zip' file, with and updated tutorial for calibrating MODFLOW 2005, compatible with hydroPSO >= 0.3-0   
          The old zip file was renamed to 'MF2005_old.zip', which is compatible with hydroPSO <= 0.1-58    
        o 'lhoat'           : -) fixed bug that led to all parameters have the same Ranking (equal to 0) when 'fn!="hydromod"' (Thanks to Rui Esteves !)
                              -) fixed bug that led to the following error message "object 'model.out.text.fname' not found" when 'write2disk=FALSE'
                              -) 'fn' argument now can be any R function or a character. In the latter case, it can be "hydromod" or the name of a 
                                  valid R function. In previous versions of 'lhoat' only a character type was accepted (Thanks to Rui Esteves !)
        o 'hydroPSO'        : if a 'parallel' directory was not successfully removed during a previous run, it is removed before running the algorithm in parallel mode again.
        o 'ReadPlot_results': updated description of the 'dp3D.names' argument    
        o 'plot_out'        : 'main' argument is not overwritten to "Observed vs 'best' Simulation" when this argument is provided and 'ptype=="ts"'
        o 'plot_results'    : 'main' argument is now (internally) passed to the 'plot_out' function.
        o 'plot_particles'  : 'main' argument is now omitted for the 3D dotty plots ('plot_NparOF' function), in order to avoid confusing (and sometimes
                              unnecessary) titles when 'main' is too long        
        o 'plot_NparOF'     : 'main' argument was disabled, in order to avoid confusing titles when 'main is a long text

0.3-0	19-Dec-2012
        o 'hydroPSO'    : -) parallel capable (OS-independent)
                             * new argument 'parallel' to define how to parallelise the evaluation of the objective function
                             * new 'control' argument 'par.nnodes'  to define the number of cores/nodes to be used in a multi-core machine or 
                               network cluster
                             * new 'control' argument 'par.pkgs' (only needed for Windows machines) with the list of package that need to be 
                               loaded on each core/node 
                          -) Default number of particles for 'method=spso2007' was changed  from 'ceiling(10+2*sqrt(n))' to 'floor(10+2*sqrt(n))', following Clerc 2012

        o New vignette (14/Dec/2012)
                             
        o 'read_out'    : -) new argument 'nsim' used to specify the number of model outputs. It is useful when the model to be calibrated returns NA
                             instead of the simulated values for some particles (e.g., MODFLOW)
                           
        o 'read_results': -) See 'read_out' above

        o 'plot_results': -) See 'read_out' above
