<h2>About ADMB and TMB</h2>
<p>The ADMB project supports the application of <a href="http://www.autodiff.org">automatic differentiation (AD)</a> for solutions to non-linear statistical modeling and optimization problems.</p>
<p><strong>AD Model Builder</strong>, or ADMB, is a statistical application that implements AD using C++ classes and a native template language. ADMB can be <a href="downloads">downloaded</a> and source code is available on <a href="https://github.com/admb-project/admb">GitHub</a>. For further information, see this site and the ADMB paper:<br/><a href="http://tandfonline.com/doi/abs/10.1080/10556788.2011.597854"><cite style="font-size:0.9em">Fournier, D.A., Skaug, H.J., Ancheta, J., Ianelli, J., Magnusson, A., Maunder, M.N., Nielsen, A., and Sibert, J. 2012. AD Model Builder: using automatic differentiation for statistical inference of highly parameterized complex nonlinear models. Optim. Methods Softw. 27:233-249.</cite></a></p>
<p><strong>Template Model Builder</strong>, or TMB, is an R package that implements AD using C++ templates. TMB can be downloaded from <a href="https://cran.r-project.org/package=TMB">CRAN</a> and is developed on <a href="https://github.com/kaskr/adcomp">GitHub</a>. For further information, see the <a href="https://github.com/kaskr/adcomp/wiki">Wiki</a> and the TMB paper:<br/><a href="https://www.jstatsoft.org/article/view/v070i05"><cite style="font-size:0.9em">Kristensen, K., Nielsen, A., Berg, C.W., Skaug, H.J., and Bell, B.M. 2016.
