DeepMining Visualization

To aid in the development of your submission, we are providing a visualization tool to competitors. This tool is provided as is, with no guarantees of any sort. The tool is packaged as an executable jar, which can be run either by double clicking it (in windows anyway) or from the command line as "java -jar Mining.jar".

As in previous contests, to use this visualization tool, you should create an application that communicates with the tool via standard in and standard out. Note that this does not effect the way your program should work when you submit it on the TopCoder website. The program that you write for the visualizer should start by reading the parameters from the standard input stream. Once you have read the parameters, you should write your moves to standard out, one move per line. The visualizer will attempt to read moves until your program returns an 'X'.

After reading the initialization parameters (one per line), you should repeatedly read exactly 7 lines of input, representing the 7 elements that would be passed to your move function.

After each set of 7 lines you should write your next move and then read another 7 lines of input.

Here is an example of what your wrapper code might look like. Your main method could read the parameters and then pass them to your move method (which would be unchanged between your visualizer code and your submission code). The readInt(), readChar() and readDouble() methods each read a line of input and parse appropriately.
            for(i = 0; i<7; i++)
                s[i] = readLine()
            ch = move(s)
        while(ch != 'X')

Using the visualizer

To use the visualizer, you must have Java 1.5 or greater installed. To run the visualizer, you can execute the command "java -jar Mining.jar". This will open up a new window containing the visualization, along with a number of controls. The first thing you will need to do is specify the executable you have made for your mining code. You may either enter its path, or select it via the button provided. If your executable requires arguments, enter them in the provided field. For example, if your executable is a Java class DeepMining.class, you should enter something like "java DeepMining" (without the quotes) in this field (replacing "java" with the full path to the Java executable if necessary). The exact details of what you enter here will depend on your language choice. In particular, in Java, you will need to make sure that the class file is in the same directory as Mining.jar, or else you will need to specify a classpath along with the executable location and class name.

Once you have the executable set properly, you can run the simulation. You may customize the test case by entering any values for the parameters that you like. The field seed is a seed for the random number generator and will allow you to repeatedly generate the same test case. Clicking the "Generate Map" button will generate the map based on your parameters. Alternatively, you can select new random values for the seed and size parameters by clicking "New Parameters and Map". If you've changed the seed, since you last generated a map, the seed you entered will be used to generate the parameters, otherwise a new seed will be generated. To test the examples from the problem statement in the same way they are tested by the TopCoder system, you simple need to use the seeds provided in the problem.

Once you've started the simulation, any output you write to standard error, along with messages from the visualization tool will appear in the text area below the visualization. You may control the speed with the slider on the top.

Command Line Options

You can specify a number of parameters on the command line to simplify the automation of testing (though you don't need to use any of them). For example, "java -jar Mining.jar -fuelTank 10000" will set fuelTank to 10000 when running the tool.
-height <height> Specify the initial height of the window
-width <width> Specify the initial width of the window
-fuelTank <fuelTank> Specify fuelTank
-cargoBay <cargoBay> Specify cargoBay
-maxMineral <maxMineral> Specify maxMineral
-costFactor <costFactor> Specify costFactor
-hole_prob <costFactor> Specify costFactor
-gob_prob <costFactor> Specify costFactor
-seed <seed> Specify the initial seed
-speed <speed> Specify the initial speed
-exec <command> Specify the command to execute your code
-novisRun the test case without the visualizer (requires -exec, implies -go)
-goStart running immediately (requires -exec)
-dropTell the visualizer to drop frames if it can't keep up
