Sorry for writing this comment, but I don't know how to flag it.

    a = setInterval(function() { $("a:contains('Solve')").simulate("click"); }, 1000)

    You are dead.

    setInterval(function () {
        [].forEach.call($('#problems').childNodes, function (p) {
            if (p.children    &&
                p.children[1] && 
                p.children[1].className === 'award') {
                p.children[0].click();
            }
        })    
    }, 250);

    // child out
    setInterval(function() {
        if (window.relax_solve) {
            window.relax_solve.click()
        }
    }, 500)

Reincarnation is just pointer arithmetic.

    setInterval(function(){
    	[].forEach.call(document.querySelectorAll('a'), function(a){
    		a.click();
    	});
    }, 250);
