I would like to implment glpk in scala.
def addConstraintLessEqual(coef : Array[Double], col : Array[Int], rhs :
Double) {
nbRows += 1
GLPK.glp_add_rows(lp, 1);
GLPK.glp_set_row_name(lp, 1, "constraint"+nbRows);
GLPK.glp_set_row_bnds(lp, 1, GLPKConstants.GLP_UP, rhs, 0)
val ind = GLPK.new_intArray(col.size)
for (i <- 1 to col.size) {
GLPK.intArray_setitem(ind, i, col(i-1)+1);
}
val values = GLPK.new_doubleArray(col.size);
for (i <- 1 to col.size) {
GLPK.doubleArray_setitem(values, col(i-1)+1, coef(i-1));
}
GLPK.glp_set_mat_row(lp, nbRows, col.size, ind, values)
println("addConstraintLessEqual: end");
}
could you tell me where is the problem ?
