80 <p>The upside-down P<sub>STOP</sub> formula (left-to-right also)
81 c<sub>s</sub>(x : i, j) is "the expected fraction of parses of s" with x from
82 i to j; expectation then uses the probabilities gotten from
83 initialization and previously gained probabilities, but these are of
84 the form P<sub>STOP</sub> and P<sub>CHOOSE</sub>, how do we translate this to inside
85 outside, which just uses the probabilities of CFG-rules?

89 <h4 id="sec-8">1.3.4 How do we know whether we are 'adjacent' or not? </h4>
91 <p>Can we even know that without the full tree?
92 </p>
93 <p>
94 if we have 
95 \Tree [<sub>b</sub> [<sub>b</sub> b <u>c</u> ] <u>d</u> ] 
96 then the lower tree [<sub>b</sub> b <u>c</u> ] is adjacent since, working your way up
97 the tree, no argument has been created to the right "yet"; while the
98 outer tree [<sub>b</sub> [<sub>b</sub> &hellip; ] <u>d</u> ] is non-adjacent, since there is something in
99 between&hellip; Is it thus always adjacent to the right if the the distance
100 is 1?
