If you would like to refer to this comment somewhere else in this project, copy and paste the following link:

The following subroutine is also needed in BasicTactic.java

public static ITactic loopOnAllPendingConditional\(final ITactic ... tactics\)\{
    // return repeat\(onAllPending\(composeUntilSuccess\(tactics\)\)\);
    return new ITactic\(\)\{

        public Object apply\(IProofTreeNode ptNode, IProofMonitor pm\) \{

            boolean modified = false;

            LinkedList&lt;IProofTreeNode&gt; nodes = new LinkedList&lt;IProofTreeNode&gt;\(Arrays.asList\(ptNode.getOpenDescendants\(\)\)\);

            while \(\! nodes.isEmpty\(\)\) \{
                IProofTreeNode node = nodes.removeFirst\(\);
                for \(ITactic tactic : tactics\) \{
                    tactic.apply\(node, pm\);
                    if \(\! node.isOpen\(\)\) \{
                        // tactic made some progress on node
                        modified = true;
                        nodes.addAll\(Arrays.asList\(node.getOpenDescendants\(\)\)\);
                    \}
                    else \{
                        break;
                    \}
                \}
            \}

            if \(modified\)\{
                return null;
            \} 
            else \{
                return "loopOnAllPendingConditional: All tactics failed";
            \}
        \}
    \};
