SIM 2.26 is great! The 1st version was released in 1983, and 2.26 in 2008.
It's very efficient as it used hash-table and some algorithms in compilers and
DNA-sequence-matching...

50%, not very reasonable and objective, I think it's better to add a new colum
'similarity' to the table to see the value...

CREATE TABLE `solution_sim` (
`solution_id` int(11) NOT NULL,
`sim_solution_id` int(11) NULL,
`sim` int(11) NULL,
PRIMARY KEY (`solution_id`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;
ALTER TABLE `solution_sim` RENAME TO `sim`,
CHANGE COLUMN `solution_id` `s_id` INTEGER NOT NULL,
CHANGE COLUMN `sim_solution_id` `sim_s_id` INTEGER DEFAULT NULL,
DROP PRIMARY KEY,
ADD PRIMARY KEY USING BTREE(`s_id`);
Here does the sim 'int' mean the sin_value * 100?
And any other index on the table needed(the 2nd colum), think for a while...?

s_id sim_s_id sim means:
solution of (s_id) is (sim)% like solution of (sim_s_id)
