The codes:

• Main codes: You need all of this stuff:
  • imfil.m
  • imfil_optset.m
• Tools and examples for the advanced options in the Imfil_Tools directory:
  build_history.m , lev_mar_exec.m , random_search.m
• Examples
  • Simple Example: driver_easy.m , driver_easy_p.m , f_easy.m , f_easy_p.m , image_easy.m , parallel_easy.m
  • Linear Constraints: explore_driver.m , lc_driver.m , lc_imfil.m , lc_obj.m , linear_constraints.m , tangent_directions.m ,
• Case studies from the book
  • Parameter ID: driver_lm.m, driver_parallel_pid.m, driver_pid.m , driver_sa.m , driver_term.m , exact_solution.m , history_test.m , parallel_pidlsq.m , pidobj.m , sa_parallel_pidlsq.m , sa_serial_pidlsq.m , , serial_pidlsq.m , yfunsp.m
  • Hydraulic Capture:
    • You will need to install MODFLOW 2000 to get this example to work. Get it from http://water.usgs.gov/nrp/gwsoftware/modflow2000/modflow2000.html
    • Be sure and get the DATA directory in DATA.tar.gz!
    • The other files are README , hcevalp.m , hceval.m , hc_driver.m , hc_driver_parallel.m , parallel_test.m , plot_landscape.m ,
  • Water Resources:
    • You will need randsample.m from the MATLAB statistics toolbox.
    • The other files are README , LRGV_Cost.m , LRGV_Parallel.m , LRGV_Cover.m , LRGV_datafile.m , LRGV_driver.m , LRGV_figs.m , plot_landscape.m
