1. http://pyamg.googlecode.com/svn/branches/1.0.x/Docs/html/pyamg.vis.html In the example forpyamg.vis.vis_coarse.vis_aggregate_group(), the line "from vis_coarse import vis_aggregate_groups" should be changed to "from pyamg.vis.vis_coarse import vis_aggregate_groups"

2. http://code.google.com/p/pyamg/wiki/PyAMGFunctionality There is a missing link in the sentence "Full documentation can be found here"

3. http://code.google.com/p/pyamg/wiki/Tutorial In a couple of paragraphs, the wording is weird/broken. (Please note that I am not a native English speaker, but) I guess the following paragraph: "Here we can see that 7 levels are constructed until a coarse level of 4 (<max_coarse=10) is found. The operator complexity (the total nnz on the fine grid compares to the total nnz on all levels) is moderates low, and the grid complexity (total dof on the finest level compared with the fine level) is low. Also the coarsest level solve set at a pseudo-inverse (pinv2).

Now we can start a places holder for the residuals, initialize a right-hand-side to Ax=b, and give the solver an initial guess x0:"

could be changed to something like: "Here we can see that 7 levels are constructed until a coarse level of 4 (<max_coarse=10) is achieved. The operator complexity (the total nnz on the fine grid compared to the total nnz on all levels) is moderately low, and the grid complexity (total dof on the finest level compared to the fine level) is low. Also the coarsest level solver is set to pseudo-inverse (pinv2).

Now we can initialize a place-holder for the residuals, set right-hand-side to Ax=b, and run the solver with initial guess x0:"

These are all duplicate issues.
